What's CAC

This repository contains a library of Content-Aware Computing (CAC) by Fujitsu.
CAC is a software technology that aims at easy, high-speed, lightweight, and accurate deep learning processing.

Contents

1. Gradient-Skip

Gradient-Skip is an approach for CNNs to skip backward calculations for layers that enouch converged.
This reduces calculations in backward and communications of gradient.
You can use Gradient-Skip by simply replacing the optimizer with our SGD.

2. Automatic Pruning

Automatic Pruning is a pruning tool for neural networks, which can determine the pruning rate of each layer automatically.

3. Synchronous-Relaxation

Relaxed Synchronization technique removes slow processes from the group of distributed training and prevent limiting overall training speed due to slow processes.

Quick Start

Linux

pip install --no-cache-dir cac

When download the code by using git clone

git clone https://github.com/FujitsuLaboratories/CAC.git
cd ./CAC             # move to the directory where 'setup.py' is located.
pip install -e .     # execute `pip install` after moving the directory.
