| Summary: | Recognising affect from visual data has long been a research interest. However, annota- tions of affect in images/videos are expensive to acquire and current datasets all have limitations of either being too small or containing imbalanced affect classes. . In other at- tempts of data augmentation for emotion recognition, generation is all modelled as image translation task. In this paper, we first analyse generative models and multiple relevant GAN variants. We then propose to boost performance of emotion recognition model by investigating two generative models with one being image translation model using GANs and the other model to generate target data distribution with latent noise as input. In this way, we can achieve richer and more flexible data augmentation. Experiments on fer2013 dataset[11] showed effectiveness of our methods. |
