ChipNet

This is the official repository to the ICLR 2021 paper "ChipNet: Budget-Aware Pruning with Heaviside Continuous Approximations" by Rishabh Tiwari, Udbhav Bamba, Arnav Chavan, Deepak Gupta.

Getting Started

You will need Python 3.7 and the packages specified in requirements.txt. We recommend setting up a virtual environment with pip and installing the packages there.

Install packages with:

$ pip install -r requirements.txt

Configure and Run

All configurations concerning data, model, training, etc. can be called using commandline arguments.

The main script offers many options; here are the most important ones:

Pretraining

usage: python pretraining.py [dataset] [model name] --epochs [number of epochs] --decay [weight decay] --batch_size [batch size] --lr [learning rate] --scheduler_type {1, 2}

Pruning

usage: python pruning.py [dataset] [model name] --Vc {float value between 0-1} --budget_type {channel_ratio, volume_ratio, parameter_ratio, flops_ratio} --epochs 20

Finetuning

usage: python finetuning.py [dataset] [model name] --Vc {float value between 0-1} --budget_type {channel_ratio, volume_ratio, parameter_ratio, flops_ratio} --name {model name}_{dataset}_{budget}_{budget_type} --epochs [number of epochs] --decay [weight decay] --batch_size [batch size] --lr [learning rate] --scheduler_type {1, 2}

Mask Transfer

usage: python finetuning.py [dataset] [model name] --Vc {float value between 0-1} --budget_type {channel_ratio, volume_ratio, parameter_ratio, flops_ratio} --host_name {model name}_{dataset}_{budget}_{budget_type} --epochs [number of epochs] --decay [weight decay] --batch_size [batch size] --lr [learning rate] --scheduler_type {1, 2}

• Parameter and FLOPs budget is supported only with models using ResNetCifar module for now.
