Title: PocketFlow: An Automated Framework for Compressing and Accelerating Deep Neural Networks

Paper content:
Deep neural networks are widely used in various domains, but the prohibitive computational complexity prevents their deployment on mobile devices.
Numerous model compression algorithms have been proposed, however, it is often difficult and time-consuming to choose proper hyper-parameters to obtain an efficient compressed model.
In this paper, we propose an automated framework for model compression and acceleration, namely PocketFlow.
This is an easy-to-use toolkit that integrates a series of model compression algorithms and embeds a hyper-parameter optimization module to automatically search for the optimal combination of hyper-parameters.
Furthermore, the compressed model can be converted into the TensorFlow Lite format and easily deployed on mobile devices to speed-up the inference.
PocketFlow is now open-source and publicly available at https://github.com/Tencent/PocketFlow.
Deep learning has been widely used in various areas, such as computer vision, speech recognition, and natural language translation.
However, deep learning models are often computational expensive, which limits further applications on mobile devices with limited computational resources.To address this dilemma between accuracy and computational complexity, numerous algorithms have been proposed to compress and accelerate deep networks with minimal performance degradation.
Commonly-used approaches include low-rank decomposition BID15 BID14 , channel pruning (a.k.a. structured pruning) BID6 BID17 , weight sparsification (a.k.a. non-structured pruning) BID16 , and weight quantization BID1 BID2 .
However, these algorithms usually involve several hyper-parameters that may have a large impact on the compressed model's performance.
It can be quite difficult to efficiently choose proper hyper-parameter combinations for different models and learning tasks.
Recently, some researches adopted reinforcement learning methods to automatically determine hyperparameters for channel pruning BID4 and weight sparsification BID5 algorithms.In this paper, we present an automated framework for compressing and accelerating deep neural networks, namely PocketFlow.
We aim at providing an easy-to-use toolkit for developers to improve the inference efficiency with little or no performance degradation.
PocketFlow has inte-grated a series of model compression algorithms, including structured/non-structured pruning and uniform/non-uniform quantization.
A hyper-parameter optimizer is incorporated to automatically determine hyper-parameters for model compression components.
After iteratively training candidate compressed models and adjusting hyper-parameters, a final compressed model is obtained to maximally satisfy user's requirements on compression and/or acceleration ratios.
The resulting model can be exported as a TensorFlow-Lite file for efficient deployment on mobile devices.
In this paper, we present the PocketFlow framework to boost the deployment of deep learning models on mobile devices.
Various model compression algorithms are integrated and hyper-parameter optimizers are introduced into the training process to automatically generate highly-accurate compressed models with minimal human effort.
