Capsule neural network is a new and popular technique in deep learning. However, the traditional capsule neural network does not extract features sufficiently before the dynamic routing between capsules. In this study, one double enhanced capsule neural network (E2-Capsnet) that uses AU-aware attention for facial expression recognition (FER) is proposed. The E2-Capsnet takes advantage of dynamic routing between capsules and has two enhancement modules which are beneficial to FER. The firstdoi:10.1049/iet-ipr.2020.0063 fatcat:xjjycm6yuvbxpndndzceiz55ne
