Abstract: Aiming to address the inadequate feature extraction problems in the traditional capsule networks (CapsNets), a multi-stage attention-based CapsNet model is proposed in this paper for image classification. Firstly, spatial attention (SA) and channel attention (CA) are used to extract effective features in the convolutional layer from low-level features and high-level features, respectively. Then, attention mechanism based on vector direction is introduced into the dynamic routing layer to enhance the focus on the important capsules, thereby improving the prediction accuracy of the low-layer capsules to the high-layer capsules. Finally, the comparison experiments on image classification are carried out on five public datasets. The experimental results show that the proposed CapsNet outperforms other CapsNets at the classification accuracy and the robustness, and its shows a good performance on the image reconstruction for affine images.-
