InfoBatch

ICLR 2024 Oral | [Paper] | [Code]

InfoBatch is a tool for lossless deep learning training acceleration. It achieves lossless training speed-up by unbiased dynamic data pruning.

News

[2024/1/17] 🔥 New version with only 3 lines of change comes! Note that one should use a per-sample loss (to update the score and calculate batch loss)

[2024/1/16] 🔥 Our work got accepted to ICLR 2024 (oral)! A new version with only 3 lines of change will be updated soon. Experiments included in the paper (and beyond) will be gradually updated with detail.

[2023/8/1] 🔥 InfoBatch can now losslessly save 40.9% on CIFAR100 and ImageNet. We are updating paper content and preparing for public code.

Install

Install InfoBatch via

pip install git+https://github.com/NUS-HPC-AI-Lab/InfoBatch

Or you can clone this repo and install it locally.

git clone https://github.com/NUS-HPC-AI-Lab/InfoBatch
cd InfoBatch
pip install -e .

Get Started

To adapt your code with InfoBatch, just download and import InfoBatch, and change the following three lines:

Note that one should use a per-sample loss to update the score and calculate batch loss; if the learning rate scheduler is epoch-based, adjust its steps accordingly at beginning of each epoch.

For research studies and more flexible codes, you can refer to the code in research.

Experiments

Cifar

To run the CIFAR-100 example with baseline, run with delta=0:

python3 examples/cifar_example.py \
  --model r50 --optimizer lars --max-lr 5.2 --delta 0.0

To run the CIFAR-100 example with InfoBatch, run the following:

python3 examples/cifar_example.py \
  --model r50 --optimizer lars --max-lr 5.2 --delta 0.875 --ratio 0.5 --use_info_batch

Our example also supports mixed precision training and distributed data parallelism with the following command:

CUDA_VISIBLE_DEVICES=0,1 python3 -m torch.distributed.launch --use_env --nnodes=1 --nproc_per_node=2 \
  --master_addr=127.0.0.1 --master_port=23456 --node_rank=0 cifar_example.py \
  --use_ddp --use_info_batch --fp16 \
  --model r50 --optimizer lars --max-lr 5.2 --delta 0.875 --ratio 0.5

You may observe a performance drop when using the Distributed Data-Parallel (DDP) training approach compared to the Data Parallel (DP) approach on multiple GPUs, especially in versions prior to Pytorch 1.11. However, this is not specific to our algorithm itself.
