Generate text using the recurrent neural network language model The language model is important in the field of natural language processing. In addition to getting the word vector (a by-product of language model training), it can also help us to generate text. Given a number of words, the language model can help us predict the next most likely word. In the example of using the language model to generate text, we focus on the recurrent neural network language model. We can use the instructions in the document quickly adapt to their training corpus, complete automatic writing poetry, automatic writing prose and other interesting models. -- 2.1 [Generate text using the annotated neural network language model] (https://github.com/PaddlePaddle/models/tree/develop/generate_sequence_by_rnn_lm) +- 2.1 [Generate text using the annotated neural network language model](https://github.com/PaddlePaddle/models/tree/develop/generate_sequence_by_rnn_lm) ## 3. Click-Through Rate prediction The click-through rate model predicts the probability that a user will click on an ad. This is widely used for advertising technology. Logistic Regression has a good learning performance for large-scale sparse features in the early stages of the development of click-through rate prediction. In recent years, DNN model because of its strong learning ability to gradually take the banner rate of the task of the banner. In the example of click-through rate estimates, we give the Google's Wide & Deep model. This model combines the advantages of DNN and the applicable logistic regression model for DNN and large-scale sparse features. -- 3.1 [Click-Through Rate Model] (https://github.com/PaddlePaddle/models/tree/develop/ctr) +- 3.1 [Click-Through Rate Model](https://github.com/PaddlePaddle/models/tree/develop/ctr) ## 4. Text classification Text classification is one of the most basic tasks in natural language processing. The deep learning method can eliminate the complex feature engineering, and use the original text as input to optimize the classification accuracy. -For text classification, we provide a non-sequential text classification model based on DNN and CNN.

Learning to rank Learning to rank (LTR) is one of the core problems in information retrieval and search engine research. Training data is used by a learning algorithm to produce a ranking model which computes the relevance of documents for actual queries. The depth neural network can be used to model the fractional function to form various LTR models based on depth learning. -The algorithms for learning to rank are usually categorized into three groups by their input representation and the loss function. These are pointwise, pairwise and listwise approaches. Here we demonstrate RankLoss loss function method (pairwise approach), and LambdaRank loss function method (listwise approach). (For Pointwise approaches, please refer to [Recommended System] (https://github.com/PaddlePaddle/book/ blob / develop / 05.recommender_system / README.cn.md)). +The algorithms for learning to rank are usually categorized into three groups by their input representation and the loss function.

Semantic model The deep structured semantic model uses the DNN model to learn the vector representation of the low latitude in a continuous semantic space, finally models the semantic similarity between the two sentences. In this example, we demonstrate how to use PaddlePaddle to implement a generic deep structured semantic model to model the semantic similarity between two strings. The model supports different network structures such as CNN (Convolutional Network), FC (Fully Connected Network), RNN (Recurrent Neural Network), and different loss functions such as classification, regression, and sequencing. -- 6.1 [Deep structured semantic model] (https://github.com/PaddlePaddle/models/tree/develop/dssm) +- 6.1 [Deep structured semantic model](https://github.com/PaddlePaddle/models/tree/develop/dssm) ## 7.
