Description: We use an ensemble of CNN models. These models are trained with different model archs (resnext, densenet), different data aug methods (cutout, mixup, rotate, random cut), different input scales and different data distributions. To generate different data distributions, we trained a gan-based generative model to create new samples and use it to adjust word distribution of training sets. We do not use any external real data.
