The script will download CIFAR-10 dataset from the official dataset. +It will convert it to jpeg images and organize them into a directory with the required structure for the tutorial.

There are 50000 training images and 10000 test images. + +Here are the classes in the dataset, as well as 10 random images from each: +
![Image Classification](./cifar.png)
+ + +After downloading and converting, we should find a directory (cifar-out) containing the dataset in the following format: + +``` +train +---airplane +---automobile +---bird +---cat +---deer +---dog +---frog +---horse +---ship +---truck +test +---airplane +---automobile +---bird +---cat +---deer +---dog +---frog +---horse +---ship +---truck +``` + +It has two directories:`train` and `test`. These two directories contain training data and testing data of CIFAR-10, respectively. Each of these two folders contains 10 sub-folders, ranging from `airplane` to `truck`. Each sub-folder contains images with the corresponding label. After the images are organized into this structure, we are ready to train an image classification model. + +## Preprocess +After the data has been downloaded, it needs to be pre-processed into the Paddle format.

If you have no gpu environment, just set `use_gpu=0`. + +- `./demo/image_classification/vgg_16_cifar.py` is the network and data configuration file. The meaning of the other flags can be found in the documentation of the command line flags. + +- The script `plotcurve.py` requires the python module of `matplotlib`, so if it fails, maybe you need to install `matplotlib`. + + +After training finishes, the training and testing error curve will be saved to `plot.png` using `plotcurve.py` script. An example of the plot is shown below: + +

Suppose our loss function is $c(y)$, then +\[\frac{\partial c(y)}{\partial x} = \frac{\partial c(y)}{\partial y} \frac{\partial y}{\partial x} \] + +Suppose $z = f(W^T x + b)$, then +\[ \frac{\partial y}{\partial z} = \frac{\partial f(z)}{\partial z}\] + This derivative can be automatically computed by our base layer class. + +Then, for fully connected layer, we need to compute $\frac{\partial z}{\partial x}$, and $\frac{\partial z}{\partial W}$, and $\frac{\partial z}{\partial b}$. +\[ \frac{\partial z}{\partial x} = W \] +\[ \frac{\partial z_j}{\partial W_{ij}} = x_i \] +\[ \frac{\partial z}{\partial b} = \mathbf 1 \] +where $\mathbf 1$ is an all one vector, $W_{ij}$ is the number at the i-th row and j-th column of the matrix $W$, $z_j$ is the j-th component of the vector $z$, and $x_i$ is the i-th component of the vector $x$. + +Then we can use chain rule to calculate $\frac{\partial z}{\partial x}$, and $\frac{\partial z}{\partial W}$. The details of the computation will be given in the next section. + +## Implement C++ Class +The C++ class of the layer implements the initialization, forward, and backward part of the layer. The fully connected layer is at `paddle/gserver/layers/FullyConnectedLayer.h` and `paddle/gserver/layers/FullyConnectedLayer.cpp`. We list simplified version of the code below. + +It needs to derive the base class `paddle::BaseLayer`, and it needs to override the following functions: + +- constructor and destructor. +- `init` function. It is used to initialize the parameters and settings. +- `forward`. It implements the forward part of the layer. +- `backward`. It implements the backward part of the layer. +- `prefetch`. It is utilized to determine the rows corresponding parameter matrix to prefetch from parameter server. You do not need to override this function if your layer does not need remote sparse update. (most layers do not need to support remote sparse update) + + +The header file is listed below: + +```C +namespace paddle { +/** + * A layer has full connections to all neurons in the previous layer. + * It computes an inner product with a set of learned weights, and + * (optionally) adds biases. + * + * The config file api is fc_layer. + */ + +class FullyConnectedLayer : public Layer { +protected: + WeightList weights_; + std::unique_ptr biases_; + +public: + explicit FullyConnectedLayer(const LayerConfig& config) + : Layer(config) {} + ~FullyConnectedLayer() {} + + bool init(const LayerMap& layerMap, const ParameterMap& parameterMap); + + Weight& getWeight(int idx) { return *weights_[idx]; } + + void prefetch(); + void forward(PassType passType); + void backward(const UpdateCallback& callback = nullptr); +}; +} // namespace paddle +``` + +It defines the parameters as class variables. We use `Weight` class as abstraction of parameters. It supports multi-thread update. The details of this class will be described in details in the implementations. +- `weights_` is a list of weights for the transformation matrices. The current implementation can have more than one inputs. Thus, it has a list of weights. One weight corresponds to an input. +- `biases_` is a weight for the bias vector. + +The fully connected layer does not have layer configuration hyper-parameters. If there are some layer hyper-parameters, a common practice is to store it in `LayerConfig& config`, and put it into a class variable in the constructor. + +The following code snippet implements the `init` function. +- First, every `init` function must call the `init` function of the base class `Layer::init(layerMap, parameterMap);`. This statement will initialize the required variables and connections for each layer. +- The it initializes all the weights matrices $W$. The current implementation can have more than one inputs. Thus, it has a list of weights. +- Finally, it initializes the bias. + + +```C +bool FullyConnectedLayer::init(const LayerMap& layerMap, + const ParameterMap& parameterMap) { + /* Initialize the basic parent class */ + Layer::init(layerMap, parameterMap); + + /* initialize the weightList */ + CHECK(inputLayers_.size() == parameters_.size()); + for (size_t i = 0; i < inputLayers_.size(); i++) { + // Option the parameters + size_t height = inputLayers_[i]->getSize(); + size_t width = getSize(); + + // create a new weight + if (parameters_[i]->isSparse()) { + CHECK_LE(parameters_[i]->getSize(), width * height); + } else { + CHECK_EQ(parameters_[i]->getSize(), width * height); + } + Weight* w = new Weight(height, width, parameters_[i]); + + // append the new weight to the list + weights_.emplace_back(w); + } + + /* initialize biases_ */ + if (biasParameter_.get() != NULL) { + biases_ = std::unique_ptr(new Weight(1, getSize(), biasParameter_)); + } + + return true; +} + +``` + + +The implementation of the forward part has the following steps. +- Every layer must call `Layer::forward(passType);` at the beginning of its `forward` function. +- Then it allocates memory for the output using `reserveOutput(batchSize, size);`. This step is necessary because we support the batches to have different batch sizes. `reserveOutput` will change the size of the output accordingly. For the sake of efficiency, we will allocate new memory if we want to expand the matrix, but we will reuse the existing memory block if we want to shrink the matrix. +- Then it computes $\sum_i W_i x + b$ using Matrix operations. `getInput(i).value` retrieve the matrix of the i-th input. Each input is a $batchSize \times dim$ matrix, where each row represents an single input in a batch. For a complete lists of supported matrix operations, please refer to `paddle/math/Matrix.h` and `paddle/math/BaseMatrix.h`. +- Finally it applies the activation function using `forwardActivation();`. It will automatically applies the corresponding activation function specifies in the network configuration. + + +```C +void FullyConnectedLayer::forward(PassType passType) { + Layer::forward(passType); + + /* malloc memory for the output_ if necessary */ + int batchSize = getInput(0).getBatchSize(); + int size = getSize(); + + { + // Settup the size of the output. + reserveOutput(batchSize, size); + } + + MatrixPtr outV = getOutputValue(); + + // Apply the the transformation matrix to each input. + for (size_t i = 0; i != inputLayers_.size(); ++i) { + auto input = getInput(i); + CHECK(input.value) << "The input of 'fc' layer must be matrix"; + i == 0 ? outV->mul(input.value, weights_[i]->getW(), 1, 0) + : outV->mul(input.value, weights_[i]->getW(), 1, 1); + } + + /* add the bias-vector */ + if (biases_.get() != NULL) { + outV->addBias(*(biases_->getW()), 1); + } + + /* activation */ { + forwardActivation(); + } +} +``` + +The implementation of the backward part has the following steps. +- ` backwardActivation();` computes the gradients of the activation. The gradients will be multiplies in place to the gradients of the output, which can be retrieved using `getOutputGrad()`. +- Compute the gradients of bias. Notice that we an use `biases_->getWGrad()` to get the gradient matrix of the corresponding parameter. After the gradient of one parameter is updated, it *MUST* call `getParameterPtr()->incUpdate(callback);`. This is utilize for parameter update over multiple threads or multiple machines. +- Then it computes the gradients of the transformation matrices and inputs, and it calls `incUpdate` for the corresponding parameter. This gives the framework the chance to know whether it has gathered all the gradient to one parameter so that it can do some overlapping work (e.g., network communication) + + +```C +void FullyConnectedLayer::backward(const UpdateCallback& callback) { + /* Do derivation for activations.*/ { + backwardActivation(); + } + + if (biases_ && biases_->getWGrad()) { + biases_->getWGrad()->collectBias(*getOutputGrad(), 1); + + /* Increasing the number of gradient */ + biases_->getParameterPtr()->incUpdate(callback); + } + + bool syncFlag = hl_get_sync_flag(); + + for (size_t i = 0; i != inputLayers_.size(); ++i) { + /* Calculate the W-gradient for the current layer */ + if (weights_[i]->getWGrad()) { + MatrixPtr input_T = getInputValue(i)->getTranspose(); + MatrixPtr oGrad = getOutputGrad(); + { + weights_[i]->getWGrad()->mul(input_T, oGrad, 1, 1); + } + } + + + /* Calculate the input layers error */ + MatrixPtr preGrad = getInputGrad(i); + if (NULL != preGrad) { + MatrixPtr weights_T = weights_[i]->getW()->getTranspose(); + preGrad->mul(getOutputGrad(), weights_T, 1, 1); + } + + { + weights_[i]->getParameterPtr()->incUpdate(callback); + } + } +} +``` + +The `prefetch` function specifies the rows that need to be fetched from parameter server during training. It is only useful for remote sparse training. In remote sparse training, the full parameter matrix is stored distributedly at the parameter server. When the layer uses a batch for training, only a subset of locations of the input is non-zero in this batch. Thus, this layer only needs the rows of the transformation matrix corresponding to the locations of these non-zero entries. The `prefetch` function specifies the ids of these rows. + +Most of the layers do not need remote sparse training function. You do not need to override this function in this case. + +```C +void FullyConnectedLayer::prefetch() { + for (size_t i = 0; i != inputLayers_.size(); ++i) { + auto* sparseParam = + dynamic_cast(weights_[i]->getW().get()); + if (sparseParam) { + MatrixPtr input = getInputValue(i); + sparseParam->addRows(input); + } + } +} +``` + +Finally, you can use `REGISTER_LAYER(fc, FullyConnectedLayer);` to register the layer. `fc` is the identifier of the layer, and `FullyConnectedLayer` is the class name of the layer. + +```C +namespace paddle { +REGISTER_LAYER(fc, FullyConnectedLayer); +} +``` + +If the `cpp` file is put into `paddle/gserver/layers`, it will be automatically compiled. + +## Implement Python Wrapper +Implementing Python wrapper allows us to use the added layer in configuration files. All the Python wrappers are in file `python/paddle/trainer/config_parser.py`. An example of the Python wrapper for fully connected layer is listed below. It has the following steps: +- Use `@config_layer('fc’)` at the decorator for all the Python wrapper class. `fc` is the identifier of the layer. +- Implements `__init__` constructor function. + - It first call `super(FCLayer, self).__init__(name, 'fc', size, inputs=inputs, **xargs)` base constructor function. `FCLayer` is the Python wrapper class name, and `fc` is the layer identifier name. They must be correct in order for the wrapper to work. + - Then it computes the size and format (whether sparse) of each transformation matrix as well as the size. + +```python +@config_layer('fc') +class FCLayer(LayerBase): + def __init__( + self, + name, + size, + inputs, + bias=True, + **xargs): + super(FCLayer, self).__init__(name, 'fc', size, inputs=inputs, **xargs) + for input_index in xrange(len(self.inputs)): + input_layer = self.get_input_layer(input_index) + psize = self.config.size * input_layer.size + dims = [input_layer.size, self.config.size] + format = self.inputs[input_index].format + sparse = format == "csr" or format == "csc" + + if sparse: + psize = self.inputs[input_index].nnz + + self.create_input_parameter(input_index, psize, dims, sparse, format) + self.create_bias_parameter(bias, self.config.size) +``` + +In network configuration, the layer can be specifies using the following code snippets. The arguments of this class are: +- `name` is the name identifier of the layer instance. +- `type` is the type of the layer, specified using layer identifier. +- `size` is the output size of the layer. +- `bias` specifies whether this layer instance has bias. +- `inputs` specifies a list of layer instance names as inputs. + +```python +Layer( + name = "fc1", + type = "fc", + size = 64, + bias = True, + inputs = [Input("pool3")] +) +``` + +You are also recommended to implement a helper for the Python wrapper, which makes it easier to write models.

It includes the following parts: + +* initalizer： define the additional meta-data of the data provider and the types of the input data. +* process： Each `yield` returns a data sample. In this case, it return the text representation and category id. The order of features in the returned result needs to be consistent with the definition of the input types in `initalizer`. + +```python +from paddle.trainer.PyDataProvider2 import * + +# id of the word not in dictionary +UNK_IDX = 0 + +# initializer is called by the framework during initialization. +# It allows the user to describe the data types and setup the +# necessary data structure for later use. +# `settings` is an object. initializer need to properly fill settings.input_types. +# initializer can also store other data structures needed to be used at process(). +# In this example, dictionary is stored in settings. +# `dictionay` and `kwargs` are arguments passed from trainer_config.lr.py +def initializer(settings, dictionary, **kwargs): + # Put the word dictionary into settings + settings.word_dict = dictionary + + # setting.input_types specifies what the data types the data provider + # generates. + settings.input_types = [ + # The first input is a sparse_binary_vector, + # which means each dimension of the vector is either 0 or 1.

The first is a list + # of ids representing a 0-1 binary sparse vector of the text, + # the second is the integer id of the label. + yield word_vector, int(label) +``` + +### Define Python Data Provider in Configuration files. +You need to add a data provider definition `define_py_data_sources2` in our network configuration. This definition specifies: + +- The path of the training and testing data (`data/train.list`, `data/test.list`). +- The location of the data provider file (`dataprovider_pow`). +- The function to call to get data. (`process`). +- Additional arguments or data. Here it passes the path of word dictionary. + +```python +from paddle.trainer_config_helpers import * + +file = "data/dict.txt" +word_dict = dict() +with open(dict_file, 'r') as f: + for i, line in enumerate(f): + w = line.strip().split()[0] + word_dict[w] = i +# define the data sources for the model. +# We need to use different process for training and prediction. +# For training, the input data includes both word IDs and labels. +# For prediction, the input data only includs word Ids. +define_py_data_sources2(train_list='data/train.list', + test_list='data/test.list', + module="dataprovider_bow", + obj="process", + args={"dictionary": word_dict}) +``` + +You can refer to the following link for more detailed examples +: Python Use Case，The detailed documentation on data format is: PyDataProviderWrapper。 + +## Network Architecture +You will describe four kinds of network architectures in this section. +
![](./PipelineNetwork_en.jpg)
+ +First, you will build a logistic regression model. Later, you will also get chance to build other more powerful network architectures. +For more detailed documentation, you could refer to: Layer documentation。All configuration files are in `demo/quick_start` directory. + +### Logistic Regression +The architecture is illustrated in the following picture: +
![](./NetLR_en.png)
+ +- You need define the data for text features. The size of the data layer is the number of words in the dictionary. + +```python +word = data_layer(name="word", size=voc_dim) +``` + +- You also need to define the category id for each example. The size of the data layer is the number of labels. + +```python +label = data_layer(name="label", size=label_dim) +``` + +- It uses logistic regression model to classify the vector, and it will output the classification error during training. + - Each layer has an *input* argument that specifies its input layer. Some layers can have multiple input layers. You can use a list of the input layers as input in that case. + - *size* for each layer means the number of neurons of the layer. + - *act_type* means activation function applied to the output of each neuron independently. + - Some layers can have additional special inputs. For example, `classification_cost` needs ground truth label as input to compute classification loss and error. +```python +# Define a fully connected layer with logistic activation (also called softmax activation). +output = fc_layer(input=word, + size=label_dim, + act_type=SoftmaxActivation()) +# Define cross-entropy classification loss and error. +classification_cost(input=output, label=label) +``` + +Performance summary: You can refer to the training and testing scripts later. In order to compare different network architectures, the model complexity and test classification error are listed in the following table: + + +

+ +### Word Embedding Model +In order to use the word embedding model, you need to change the data provider a little bit to make the input words as a sequence of word IDs. The revised data provider is listed below. You only need to change initializer() for the type of the first input. It is changed from sparse_binary_vector to sequence of intergers. process() remains the same. This data provider can also be used for later sequence models. + +```python +def initializer(settings, dictionary, **kwargs): + # Put the word dictionary into settings + settings.word_dict = dictionary + settings.input_types = [ + # Define the type of the first input as a sequence of integers. + integer_value_sequence(len(dictionary)), + # Define the second input for label id + integer_value(2)] + +@provider(init_hook=initializer) +def process(settings, file_name): + ... + # omitted, it is same as the data provider for LR model +``` + +This model is very similar to the framework of logistic regression, but it uses word embedding vectors instead of a sparse vectors to represent words. +
![](./NetContinuous_en.png)
+ +- It can look up the dense word embedding vector in the dictionary (its words embedding vector is `word_dim`). The input is a sequence of N words, the output is N word_dim dimensional vectors. + +```python +emb = embedding_layer(input=word, dim=word_dim) +``` + +- It averages all the word embedding in a sentence to get its sentence representation. + +```python +avg = pooling_layer(input=emb, pooling_type=AvgPooling()) +``` + +The other parts of the model are the same as logistic regression network. + +The performance is summarized in the following table:： + + +

+ +### Convolutional Neural Network Model +Convolutional neural network converts a sequence of word embeddings into a sentence representation using temporal convolutions. You will transform the fully connected layer of the word embedding model to 3 new sub-steps. +
![](./NetConv_en.png)
+ + +Text convolution has 3 steps: +1. Get K nearest neighbor context of each word in a sentence, stack them into a 2D vector representation. +2. Apply temporal convolution to this representation to produce a new hidden_dim dimensional vector. +3. Apply max-pooling to the new vectors at all the time steps in a sentence to get a sentence representation. + +```python +# context_len means convolution kernel size. +# context_start means the start of the convolution. It can be negative. In that case, zero padding is applied. +text_conv = sequence_conv_pool(input=emb, + context_start=k, + context_len=2 * k + 1) +``` + +The performance is summarized in the following table： + + +

SRL is useful as an intermediate step in a wide range of natural language processing tasks, such as information extraction. automatic document categorization and question answering. An instance is as following [1]: + + + [ A0 He ] [ AM-MOD would ][ AM-NEG n’t ] [ V accept] [ A1 anything of value ] from [A2 those he was writing about ]. + +- V: verb +- A0: acceptor +- A1: thing accepted +- A2: accepted-from +- A3: Attribute +- AM-MOD: modal +- AM-NEG: negation + + +Given the verb "accept", the chunks in sentence would play certain semantic roles. Here, the label scheme is from Penn Proposition Bank. + +To this date, most of the successful SRL systems are built on top of some form of parsing results where pre-defined feature templates over the syntactic structure are used. This tutorial will present an end-to-end system using deep bidirectional long short-term memory (DB-LSTM)[2] for solving the SRL task, which largely outperforms the previous state-of-the-art systems. The system regards SRL task as the sequence labelling problem. + + +## Data Description +The relevant paper[2] takes the data set in CoNLL-2005&2012 Shared Task for training and testing. Accordingto data license, the demo adopts the test data set of CoNLL-2005, which can be reached on website. + +To download and process the original data, user just need to execute the following command: + +```bash +cd data +./get_data.sh +``` +Several new files appear in the `data `directory as follows. +```bash +conll05st-release：the test data set of CoNll-2005 shared task +test.wsj.words：the Wall Street Journal data sentences +test.wsj.props: the propositional arguments +src.dict：the dictionary of words in sentences +tgt.dict：the labels dictionary +feature: the extracted features from data set +``` + + +## Training +### DB-LSTM +Please refer to the Sentiment Analysis demo to learn more about the long short-term memory unit. + +Unlike Bidirectional-LSTM that used in Sentiment Analysis demo, the DB-LSTM adopts another way to stack LSTM layer. First a standard LSTM processes the sequence in forward direction. The input and output of this LSTM layer are taken by the next LSTM layer as input, processed in reversed direction. These two standard LSTM layers compose a pair of LSTM. Then we stack LSTM layers pair after pair to obtain the deep LSTM model. + +The following figure shows a temporal expanded 2-layer DB-LSTM network. +

+ + + +### Features +Two input features play an essential role in this pipeline: predicate (pred) and argument (argu). Two other features: predicate context (ctx-p) and region mark (mr) are also adopted. Because a single predicate word can not exactly describe the predicate information, especially when the same words appear more than one times in a sentence. With the predicate context, the ambiguity can be largely eliminated. Similarly, we use region mark mr = 1 to denote the argument position if it locates in the predicate context region, or mr = 0 if does not. These four simple features are all we need for our SRL system. Features of one sample with context size set to 1 is showed as following[2]: +

+ +In this sample, the coresponding labelled sentence is: + +[ A1 A record date ] has [ AM-NEG n't ] been [ V set ] . + +In the demo, we adopt the feature template as above, consists of : `argument`, `predicate`, `ctx-p (p=-1,0,1)`, `mark` and use `B/I/O` scheme to label each argument. These features and labels are stored in `feature` file, and separated by `\t`. + +### Data Provider + +`dataprovider.py` is the python file to wrap data. `hook()` function is to define the data slots for network.

One simple example is to classify the customer reviews in a shopping website, a tourism website, and group buying websites like Amazon, TaoBao, Tmall etc. + +Sentiment analysis is also used to monitor social media based on large amount of reviews or blogs. For example, the researchers analyzed several surveys on consumer confidence and political opinion, found they correlate to sentiment word frequencies in contemporaneous Twitter messages [1]. Another example is to forecast stock movements through analyzing the text content of a daily Twitter blog [2]. + +On the other hand, grabbing the user comments of products and analyzing their sentiment are useful to understand user preferences for companies, products, even competing products. + +This tutorial will guide you through the process of training a Long Short Term Memory (LSTM) Network to classify the sentiment of sentences from [Large Movie Review Dataset](http://ai.stanford.edu/~amaas/data/sentiment/), sometimes known as the [Internet Movie Database (IMDB)](http://ai.stanford.edu/~amaas/papers/wvSent_acl2011.pdf). This dataset contains movie reviews along with their associated binary sentiment polarity labels, namely positive and negative. So randomly guessing yields 50% accuracy. + +## Data Preparation + +### IMDB Data Introduction + +Before training models, we need to preprocess the data and build a dictionary. First, you can use following script to download IMDB dataset and [Moses](http://www.statmt.org/moses/) tool, which is a statistical machine translation system. We provide a data preprocessing script, which is capable of handling not only IMDB data, but also other user-defined data. In order to use the pre-written script, it needs to move labeled train and test samples to another path, which has been done in `get_imdb.sh`. + +``` +cd demo/sentiment/data +./get_imdb.sh +``` +If the data is obtained successfuly, you will see the following files at ```./demo/sentiment/data```: + +``` +aclImdb get_imdb.sh imdb mosesdecoder-master +``` + +* aclImdb: raw dataset downloaded from website. +* imdb: only contains train and test data. +* mosesdecoder-master: Moses tool. + +IMDB dataset contains 25,000 highly polar movie reviews for training, and 25,000 for testing. A negative review has a score ≤ 4 out of 10, and a positive review has a score ≥ 7 out of 10. After running `./get_imdb.sh`, we can find the dataset has the following structure in `aclImdb`. + +``` +imdbEr.txt imdb.vocab README test train +``` +* train: train sets. +* test : test sets. +* imdb.vocab: dictionary. +* imdbEr.txt: expected rating for each token in imdb.vocab. +* README: data documentation. + +Both train and test set directory contains: + +``` +labeledBow.feat neg pos unsup unsupBow.feat urls_neg.txt urls_pos.txt urls_unsup.txt +``` + +* pos: positive samples, contains 12,500 txt files, each file is one movie review. +* neg: negative samples, contains 12,500 txt files, each file is one movie review. +* unsup: unlabeled samples, contains 50,000 txt files. +* urls_xx.txt: urls of each reviews. +* xxBow.feat: already-tokenized bag of words (BoW) features. + +### IMDB Data Preparation + +In this demo, we only use labled train and test set and not use imdb.vocab as dictionary. By default, dictionary is builded on train set. Train set is shuffled and test set is not. `tokenizer.perl` in Moses tool is used to tokenize the words and punctuation. Simply execute the following command to preprcess data. + +``` +cd demo/sentiment/ +./preprocess.sh +``` +preprocess.sh: + +``` +data_dir="./data/imdb" +python preprocess.py -i data_dir +``` + +* data_dir: input data directory. +* preprocess.py: preprocess script. + +If running successfully, you will see `demo/sentiment/data/pre-imdb` directory as follows: + +``` +dict.txt labels.list test.list test_part_000 train.list train_part_000 +``` +* test\_part\_000 and train\_part\_000: all labeled test and train sets. Train sets have be shuffled. +* train.list and test.list: train and test file lists. +* dict.txt: dictionary generated on train sets by default. +* labels.txt: neg 0, pos 1, means label 0 is negative review, label 1 is positive review. + +### User-defined Data Preparation + +If you perform other sentiment classifcation task, you can prepare data as follows. We have provided the scripts to build dictionary and preprocess data. So just organize data as follows. + +``` +dataset +|----train +| |----class1 +| | |----text_files +| |----class2 +| | |----text_files +| | ... +|----test +| |----class1 +| | |----text_files +| |----class2 +| | |----text_files +| | ... +``` +* dataset: 1st directory. +* train, test: 2nd directory. +* class1,class2,...: 3rd directory. +* text_files: samples with text file format. + +All samples with text files format under the same folder are same category. Each text file contains one or more samples and each line is one sample. In order to shuffle fully, the preprocessing is a little different for data with multiple lines in one text file, which needs to set `-m True` in `preprocess.sh`. And tokenizer.perl is used by default. If you don't need it, only set `-t False` in `preprocess.sh'. + +## Training + +In this task, we use Recurrent Neural Network (RNN) of LSTM architecure to train sentiment analysis model. LSTM model was introduced primarily in order to overcome the problem of vanishing gradients. LSTM network resembles a standard recurrent neural network with a hidden layer, but each ordinary node in the hidden layer is replaced by a memory cell. Each memory cell contains four main elements: an input gate, a neuron with a self-recurrent connection, a forget gate and an output gate. More details can be found in the literature [4]. The biggest advantage of the LSTM architecture is that it learns to memorize information over long time intervals without the loss of short time memory. At each time step with a new coming word, historical information stored in the memory block is updated to iteratively learn the sequence representation. + +

+ +Sentiment analysis is among the most typical problems in natural language understanding. It aims at predicting the attitude expressed in a sequence. Usually, only some key words, like adjectives and adverbs words, play a major role in predicting the sentiment of sequences or paragraphs. However, some review or comment contexts are very long, such as IMDB dataset. We use LSTM to perform this task for its improved design with the gate mechanism. First, it is able to summarize the representation from word level to context level with variable context length which is adapted by the gate values. Second, it can utilize the expanded context at the sentence level, while most methods are good at utilizing n-gram level knowledge. Third, it learns the paragraph representation directly rather than combining the context level information. This results in this end-to-end framework. + +In this demo we provide two network, namely bidirectional-LSTM and three layers of stacked-LSTM. + +#### Bidirectional-LSTM + +One is a bidirectional LSTM network, connected by fully connected layer and softmax, as shown in Figure 2. + +
![BiLSTM](./bi_lstm.jpg)
+

+ +#### Stacked-LSTM +Another is three-layer LSTM structure in Figure 3. The bottom of the figure is word embedding. Next, three LSTM-Hidden layers are connected and the second LSTM is reversed. Then extract the maximum hidden vectors of all time step of hidden and LSTM layer as the representation for the entire sequence. Finally, a fully connected feed forward layer with softmax activation is used to perform the classification task. This network is refered to paper [5]. + +

Recently proposed NMT models often belong to a family of encoder–decoder models. Encoder-Decoder models encode a source sentence into a fixed-length vector from which a decoder generates a target sentence. + +In this task, we use an extension to the encoder–decoder model which learns to align and translate jointly. Each time the model generates a word in a translation, it searches for a set of positions in the source sentence for the most relevant information. The decoder predicts a target word based on the context vectors associated with these source positions and all the previous generated target words. For more detailed explanation, readers can refer to paper [Neural Machine Translation by Jointly Learning to Align and Translate](http://arxiv.org/abs/1409.0473). + +The most distinguishing feature of this model is that it doesn't encode an input sentence into a single fixed-length vector. Instead, it encodes the input sentence into a sequence of vectors, where one vector corresponds to an input element. A subset of these vectors is chosen adaptively while decoding the translated sentence. This frees a NMT model from having to squash all the information of a source sentence, regardless of its length, into a fixed-length vector. The improvement of this model is more apparent for longer sentences, but the improvement can be observed for sentences of any length. +

+ +### Training Model in PaddlePaddle ### +We need to create a model config file before training. Here is an example `demo/seqToseq/translation/train.conf`.

It returns train_conf as the configuration, following is its input arguments: + - data_dir: directory of train data and test data + - is\_generating: whether this config is used for generating, here is false +2. **Algorithm Configuration**: We use the SGD training algorithm (default), ADAM learning method in our example, specify batch_size as 50, and learning rate as 5e-4. +3. **Network Architecture**: We use an attention version of GRU Encoder-Decoder network in our example. It consists a bidirectional GRU as an encoder and a decoder that emulates searching through a source sentence during decoding a translation. + +### Training Command and Result### +After writing the model config, we can train the model by running the command: + +```bash +cd demo/seqToseq/translation +./train.sh +``` + +The `train.sh` is shown as follows: + +```bash +paddle train \ +--config='translation/train.conf' \ +--save_dir='translation/model' \ +--use_gpu=false \ +--num_passes=16 \ +--show_parameter_stats_period=100 \ +--trainer_count=4 \ +--log_period=10 \ +--dot_period=5 \ +2>&1 | tee 'translation/train.log' +``` +- config: set config of neural network +- save_dir: set output path to save models +- use_gpu: whether to use GPU to train, here use CPU +- num_passes: set number of passes.

In the training process, the current word is always knowns as the ground truth, by contrast. In the generating process, the current word is the output of the decoder in last time step, which is accessed to from a memory in PaddlePaddle. + +Besides, we use Beam Search to generate sequences. Beam search uses breadth-first search to build its search tree. At each level of the tree, it generates all successors of the states at the current level, sorting them in increasing order of heuristic cost. However, it only stores a predetermined number of best states at each level (called the beam size). + +### Pretrained model ### +We trained the model on a cluster with 50 nodes, each node has two 6-core CPUs. We trained 16 passes in 5 days, where each pass takes 7 hours. The model_dir has 16 sub-folder, each of which contains the whole model parameters with 202MB size. And we find pass-00012 model has the highest BLEU 27.77 (see paper [BLEU: a Method for Automatic Evaluation of Machine Translation](http://www.aclweb.org/anthology/P02-1040.pdf)). To download and extract this model, simply run the following commands in linux. + +```bash +cd demo/seqToseq/data +./wmt14_model.sh +``` + +### Generating Model in PaddlePaddle ### +We need to create a model config file before translating French sequence. Here is an example `demo/seqToseq/translation/gen.conf`, the first three lines import python function for defining network, and define the job\_mode and attention\_mode. + +```python +from seqToseq_net import * +is_generating = True + +################## Data Definiation ##################### +gen_conf = seq_to_seq_data(data_dir = "./data/pre-wmt14", + is_generating = is_generating, + gen_result = "./translation/gen_result") + +############## Algorithm Configuration ################## +settings( + learning_method = AdamOptimizer(), + batch_size = 1, + learning_rate = 0) + +################# Network configure ##################### +gru_encoder_decoder(gen_conf, is_generating) +``` + +1. **Data Definiation**: We defines an SeqToSeq gen data in our example. It returns gen_conf as the configuration, following is its input arguments: + - data\_dir: directory of gen data + - is\_generating: whether this config is used for generating, here is false + - gen\_result: file to store the generation result +2. **Algorithm Configuration**: We use SGD traing algorithm in generation, and specify batch_size as 1 (each time generate one sequence), and learning rate as 0. +3. **Network Architecture**: Essentially the same as the training model. + +### Generating Command and Result ### +After writing the model config, we can do text translation from French to English by running the command: + +```bash +cd demo/seqToseq/translation +./gen.sh +``` + +The `gen.sh` is shown as follows, unlike training, there are some different arguments to specify: + +```bash +paddle train \ +--job=test \ +--config='translation/gen.conf' \ +--save_dir='data/wmt14_model' \ +--use_gpu=true \ +--num_passes=13 \ +--test_pass=12 \ +--trainer_count=1 \ +2>&1 | tee 'translation/gen.log' +``` +- job: set job mode to test +- num_passes and test_pass: loading model parameters from test_pass to (num_passes - 1), here only loads `data/wmt14_model/pass-00012` + +You will see messages like this: + + I0706 14:48:31.178915 31441 GradientMachine.cpp:143] Loading parameters from data/wmt14_model/pass-00012 + I0706 14:48:40.012039 31441 Tester.cpp:125] Batch=100 samples=100 AvgCost=0 + I0706 14:48:48.898632 31441 Tester.cpp:125] Batch=200 samples=200 AvgCost=0 + ... + +And the generating result in `demo/seqToseq/translation/gen_result` likes: + + 0 + 0 -11.1314 The about the width of the seats while large controls are at stake + 1 -11.1519 The on the width of the seats while large controls are at stake + 2 -11.5988 The about the width of the seats while large controls are at stake . + + 1 + 0 -24.4149 The dispute is between the major aircraft manufacturers about the width of the tourist seats on the flights , paving the way for a confrontation during the month of the Dubai . + 1 -26.9524 The dispute is between the major aircraft manufacturers about the width of the tourist seats on the flights , paving the way for a confrontation during the month of Dubai ' s . + 2 -27.9574 The dispute is between the major aircraft manufacturers about the width of the tourist seats on the flights , paving the way for a confrontation during the month of Dubai ' s Dubai . + ... + +- This is the beam search result, where beam size is 3 +- '0' in 1st-line and '1' in 6th-line mean the sequence-id in gen data +- Other six lines list the beam search results + - The 2nd-column is the score of beam search (from large to small) + - The 3rd-colunm is the generating English sequence +- There is 2 special tokens: + - ``: the end of a sequence + - ``: a word not included in dictionary + +### Bleu Evalutaion ### +Human evaluations of machine translation are extensive but expensive. Paper [BLEU: a Method for Automatic Evaluation of Machine Translation](http://www.aclweb.org/anthology/P02-1040.pdf) presents a method as an automated understudy to skilled human judges which substitutes for them when there is need for quick or frequent evaluations. [Moses](http://www.statmt.org/moses/) is a statistical machine translation system, and we use [multi-bleu.perl](https://github.com/moses-smt/mosesdecoder/blob/master/scripts/generic/multi-bleu.perl) of it to do Bleu Evalution. To download this script, simply run the following command: + +```bash +cd demo/seqToseq/translation +./moses_bleu.sh +``` + +Since the standard translation is alrealy downloaded as `data/wmt14/gen/ntst14.trg`, we can do Bleu Evalution by running the command: + +```bash +cd demo/seqToseq/translation +./eval_bleu.sh FILE BEAMSIZE +``` + +- FILE: the generation result file +-
