Abstract

This paper provides a mixed attention network for remote sensing image classification whose idea comes from VQA methods. In this way, it could deal with more complex requests beyond just identifying what is in the picture. The HAN (Hierarchial Attention Network) consists of an attention model to detect details on one hand and a self-attention model to detect global information on the other hand. Through attention heat maps we could see division of work is really effective and the HAN has a great performance on NWPU-RESISC45 data set. Furthermore, we may add some other subnetworks to reinforce this ability in the future.
