2. Installation

1. First clone the repository

   git clone https://github.com/XiaoyuanGuo/CVAD.git
   

2. Create the virtual environment via conda

   conda create -n cvad python=3.7 
   

3. Activate the virtual environment.

   conda activate cvad
   

4. Install the dependencies.

   pip install --user --requirement requirements.txt
   

3. Experiment

To train the model on CIFAR10/SIIM-ISIC datasets, run the following commands:

CIFAR10

python -u main.py cifar10 CVAD ./ --channel 3 --cvae_n_epochs 100 --cls_n_epochs 20 --normal_class 0 

SIIM-ISIC

To use the model for SIIM-ISIC dataset, please download the data from https://www.kaggle.com/c/siim-isic-melanoma-classification/data into ./data/ folder.

python -u main.py siim CVAD ./ --channel 3 --cvae_n_epochs 100 --cls_n_epochs 20
