cacgan's Introduction

Classic Augmentation Based Classifier Generative Adversarial Network (CACGAN) for COVID-19 Diagnosis

  • Trained the Generator with a custom loss function to enable it to generate new data in specific classes
  • Trained the Discriminator with the original data set and the data generated by the Generator
  • Evaluated the performance of the GAN model by multiple classifiers (VGG, ResNet, EfficientNet, etc.)

Configuration

  • conda env create -f environment_dl.yml
  • environment_dl.yml may contains some packages that won't be used here! If you are disk-sensitive, please only install the packages appeared in scripts :)

Usage

  • ClassicHistEqual.ipynb for histogram equalization and ClassicAUG.ipynb for classic augmentation
  • CACGAN_AUG.ipynb for data synthetizing using an AC-GAN model
  • GenerateData.ipynb for generating new data to ./GANGEN through the Generator saved during training
  • folders [augmented, original, synthetic] are results of multiple classifiers on augmented data, original data, and synthetic data, respectively
