Towards Better Selective Classification

This is the official implementation of the paper Towards Better Selective Classification.

In this work, we confirm that the superior performance of state-of-the-art methods such as SelectiveNet, Deep Gamblers, and Self-Adaptive Training is owed to training a more generalizable classifier rather than their proposed selection mechanisms. We propose an entropy-based regularizer that improves the performance and achieves new state-of-the-art results.

Install

Create and activate a conda environment. Install the dependencies as listed in requirements.txt:

conda create --name sel_cls python=3.7
conda activate sel_cls
pip install -r requirements.txt

Training and Evaluation

Self-Adaptive Training (SAT):

bash run_${dataset}.sh

Self-Adaptive Training (SAT) + Entropy Minimization (EM):

bash run_${dataset}_entropy.sh
