PRISM

PyTorch implementation of PRISM: A Self-Supervised Learning Framework using Causal Mechanism for use in Single Domain Generalization Project. TY

Including support for:

• Distributed data parallel training

• Global batch normalization

• LARS (Layer-wise Adaptive Rate Scaling) optimizer.

• Reference Code (https://github.com/Spijkervet/SimCLR)

Quickstart (fine-tune linear classifier)

Training ResNet encoder:

Distributed Training

With distributed data parallel (DDP) training:

CUDA_VISIBLE_DEVICES=0 python main.py --nodes 2 --nr 0
CUDA_VISIBLE_DEVICES=1 python main.py --nodes 2 --nr 1
CUDA_VISIBLE_DEVICES=2 python main.py --nodes 2 --nr 2
CUDA_VISIBLE_DEVICES=N python main.py --nodes 2 --nr 3

Results

Pre-trained models

ResNet (batch_size, epochs)	Optimizer	STL-10 Top-1
ResNet18(64,100)	LARS	[TODO]

LARS optimizer

The LARS optimizer is implemented in modules/lars.py. It can be activated by adjusting the config/config.yaml optimizer setting to: optimizer: "LARS". It is still experimental and has not been thoroughly tested. (From https://github.com/Spijkervet/SimCLR)
