ExpVAE

Overview

This repository provides training and testing code and data for CVPR 2020 paper:

"Towards Visually Explaining Variational Autoencoders", Wenqian Liu, Runze Li, Meng Zheng, Srikrishna Karanam, Ziyan Wu, Bir Bhanu, Richard J. Radke, and Octavia Camps

Requirements

• PyTorch 1.0
• Python 3.7
• Cuda 9.0

Running codes

• Start trainning a one-class VAE with default settings by call:

python train_expVAE.py 

other options are:

[-h] [--result_dir DIR] [--ckpt_dir DIR] [--batch_size N] [--epochs N] 
     [--seed S] [--resume PATH] [--latent_size N] [--one_class N]

Here result_dir saves validating visualizations; ckpt_dir saves best model after each epoch; latent_size decides VAE's latent vector shape; one_class decides which digit to be used as inlier to train on.

• Start testing with default settings by call:

python test_expVAE.py

other options are:

[-h] [--result_dir DIR] [--batch_size N] [--seed S]
     [--latent_size N] [--model_path DIR] [--one_class N]

Here one_class decides the outlier digit, so that expVAE will generate anomaly localization attention maps, in which high response regions denote the difference between the outlier digit and the inlier digit.

Pretrained models for MNIST can be found here
