For debug information, please use [`VLOG`](http://htmlpreview.github.io/?https://github.com/google/glog/blob/master/doc/glog.html#verbose). The reason is at [here](https://groups.google.com/a/chromium.org/d/msg/chromium-dev/3NDNd1KzXeY/AZKMMx37fdQJ). + +`VLOG` requires a *verbose level* parameter. For example: + +```c++ +VLOG(3) << "Operator FC is taking " << num_inputs << "inputs." +``` + +When we run a PaddlePaddle application or test, we can specify a verbose threshold. For example: + +```bash +GLOG_vmodule=buddy_allocator=2 \ +GLOG_v=10 \ +python \ +../python/paddle/v2/framework/tests/test_recurrent_op.py +``` + +This will enable VLOG messages generated by `buddy_allocator.{h,cc}` and in the verbose range of 0 to 3, so you will see above example VLOG message, which is in level 3. This suggests that we output overall messages in lower verbose levels, so they display with higher probability.

+ +We propose averaging for any optimizer similar to how ASGD performs it, as mentioned above. + +### How to perform Parameter Averaging in PaddlePaddle + +Parameter Averaging in PaddlePaddle works in the following way during training : +1. It will take in an instance of a normal optimizer as an input, e.g. RMSPropOptimizer +2. The optimizer itself is responsible for updating the parameters. +3. The ParameterAverageOptimizer maintains a separate copy of the parameters for itself: + 1. In concept, the values of this copy are the average of the values of the parameters in the most recent N batches. + 2. However, saving all the N instances of the parameters in memory is not feasible. + 3. Therefore, an approximation algorithm is used. + +Hence, overall we have have two copies of the parameters: one for the optimizer itself, and one for the ParameterAverageOptimizer. The former should be used in back propagation, while the latter should be used during testing and should be saved. + +During the testing/ saving the model phase, we perform the following steps: +1. Perform the delayed operations. +2. Save current values of the parameters to a temporary variable. +3. Replace the values of the parameters with the averaged values. +4. Perform testing and/or save the parameters. +5. Restore the values of the parameters once done. + +### How to implement Averaging of Parameter in PaddlePaddle + +We can add the ParameterAverageOptimizer op to the graph through Python API. Using this approach, we manually add this op to the graph and direct the output of the optimizer op to this op during training. + + **Advantages**: + - Allows for greater flexibility to the users of PaddlePaddle. Using this approach, the users can plug different optimizers into ParameterAverageOptimizer by passing in the optimizer to the op. + - Makes it easy for the users to customize and extend the framework. + + **Disadvantages**: + - Implementation requires re-writing the averaging methodology in Python. + +### Low-Level implementation + +In the new design, we propose to create a new operation for averaging parameter updates (ParameterAverageOptimizer). For now, we can add an op that takes in the following as input: +- the optimizer +- the window_size to keep the updates + +The ParameterAverageOptimizer op can be like any other operator with its own CPU/GPU implementation either using Eigen or separate CPU and GPU kernels. As the initial implementation, we can implement the kernel using Eigen following the abstraction pattern implemented for [Operators](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/operators/rmsprop_op.h). We also want to support the case when the Trainer/Optimizer runs on the GPU while ParameterAverageOptimizer runs on a CPU. + +The idea of building an op for averaging is in sync with the refactored PaddlePaddle philosophy of using operators to represent any computation unit. The way the op will be added to the computation graph will be decided by the [layer functions](https://github.com/PaddlePaddle/Paddle/blob/develop/doc/design/python_api.md#layer-function) in Python API. + +### Python API implementation for ParameterAverageOptimizer + +Based on Polyak and Juditsky (1992), we can generalize the averaging of updates to any optimizer. The input to the op would be the following: +- Any optimizer (RMSProp , AdaGrad etc.) +- A window size.

Many strategies are used by machine learning practitioners to reduce the test error, possibly at the expense of increased training error. These strategies are collectively known as **regularization**. +A central problem in machine learning is how to design an algorithm that will perform well not just on the training data, but also on new data. A frequently faced problem is the problem of **overfitting**, where the model does not make reliable predictions on new unseen data. **Regularization** is the process of introducing additional information in order to prevent overfitting. This is usually done by adding extra penalties to the loss function that restricts the parameter spaces that an optimization algorithm can explore. ### Parameter Norm Penalties Most common regularization approaches in deep learning are based on limiting the capacity of the models by adding a parameter norm penalty to the objective function `J`. This is given as follows: @@ -18,52 +18,21 @@ The most commonly used norm penalties are the L2 norm penalty and the L1 norm pe ##### L1 Regularization

Making regularization a part of the optimizer using an attribute like `weight_decay` that is used to control the scale of the L2 Penalty. This approach is used in PyTorch as follows: - ```python - opt = torch.optim.SGD(params, lr=0.2, weight_decay=0.2) - ``` - At every optimization step, this code will add the gradient of the L2 Norm of the params to the gradient of the params with respect to the loss function. This can seen in the following code snippet: - ```python - if weight_decay != 0: - d_p.add_(weight_decay, p.data) - ``` - This is a very restyrictive way of doing regularization and does not give the users enough flexibility. - - **Advantages**: - - It is easy to implement for us. - - Faster execution of backward. However, it can be done manually by advanced users too. - - **Disadvantages**: - - Not flexible for other regularizations such as L1/L0 regularization. - - Does not allow for different regularization coefficient for different parameters. For example, in most models, ony the weight matrices are regularized and the bias vectors are unregularized. - - Tightly coupled optimizer and regularization implementation. - - -2. Adding regularization ops to the graph through Python API. This approach is used by Tensorflow and Caffe. Using this approach, we manually add regularization ops to the graph and then add the regularization loss to the final loss function before sending them to the optimizer. - - **Advantages**: - - Allows for greater flexibility to the users of Paddle. Using this approach, the users can put different regularization to different parameters and also choose parameters that are not a part of regularization. - - Makes it easy for the users to customize and extend the framework. - - **Disadvantages**: - - Implementation requires comprehensive design and time. +A detailed survey of regularization in various deep learning frameworks can be found [here](https://github.com/PaddlePaddle/Paddle/wiki/Regularization-Survey). ## Proposal for Regularization in PaddlePaddle ### Low-Level implementation -In the new design, we propose to create new operations for regularization.

CRF learns the conditional probability \f$P(Y|X)\f$, where +\f$X = (x_1, x_2, ... , x_n)\f$ are structured inputs and +\f$Y = (y_1, y_2, ... , y_n)\f$ are labels for the inputs. + +Linear chain CRF is a special case of CRF that is useful for sequence labeling +task. Sequence labeling tasks do not assume a lot of conditional +independences among inputs. The only constraint they impose is that the input +and output must be linear sequences. Thus, the graph of such a CRF is a simple +chain or a line, which results in the linear chain CRF. + +This operator implements the Forward-Backward algorithm for the linear chain +CRF. Please refer to http://www.cs.columbia.edu/~mcollins/fb.pdf and +http://cseweb.ucsd.edu/~elkan/250Bwinter2012/loglinearCRFs.pdf for details. + +Equation: +1.

The next D values of Input(Transition) of this operator are for ending +weights, denoted as \f$b\f$ here. +4. The remaning values of Input(Transition) are for transition weights, +denoted as \f$w\f$ here. +5. Denote Input(Label) as \f$s\f$ here. + +The probability of a sequence \f$s\f$ of length \f$L\f$ is defined as: +\f$P(s) = (1/Z) \exp(a_{s_1} + b_{s_L} + + \sum_{l=1}^L x_{s_l} + + \sum_{l=2}^L w_{s_{l-1},s_l})\f$ +where \f$Z\f$ is a normalization value so that the sum of \f$P(s)\f$ over +all possible sequences is \f$1\f$, and \f$x\f$ is the emission feature weight +to the linear chain CRF. + +Finally, the linear chain CRF operator outputs the logarithm of the conditional +likelihood of each training sample in a mini-batch. + +NOTE: +1. The feature function for a CRF is made up of the emission features and the +transition features. The emission feature weights are NOT computed in +this operator.
