Pytorch implementation of ACLS

This is the implementation of the paper "ACLS:Adaptive and Conditional Label Smoothing for Network Calibration".

For detailed information, please checkout the project site [website] or the paper [arXiv].

Requirements

This repository has been tested with the following libraries:

  • Python = 3.6
  • PyTorch = 1.8.0

Getting started

Installation

pip install -e .

Datasets

The structure should be organized as follows:

Tiny-ImageNet

└── /dataset/tiny-imagenet-200
    ├── test
    ├── train
    ├── val
    │   ├── images
    │   └── val_annotations.txt
    ├── wninds.txt
    └── words.txt

ImageNet

├── /dataset/ILSVRC2012
└── data
    ├── train
    ├── val
    └── ILSVRC2012_devkit_t12

Training

Tiny-ImageNet

sh tools/run_tiny.sh

ImageNet

sh tools/run_imagenet.sh

Testing

Tiny-ImageNet

python tools/test.py data=tiny_imagenet hydra.run.dir=your/weight/directory test.checkpoint=your_weight.pth
