Abstract : We propose "Areas of Attention" , a novel attention-based model for automatic image caption generation. Our approach models the interplay between the state of the RNN, image region descriptors and word embedding vectors by three pairwise interactions. It allows association of caption words with local visual appearances rather than with descriptors of the entire scene. This enables better generalization to complex scenes not seen during training. Our model is agnostic to the type of attention areas, and we instantiate it using regions based on CNN activation grids, object proposals, and spatial transformer networks. Our results show that all components of our model contribute to obtain state-of-the-art performance on the MSCOCO dataset. In addition, our results indicate that attention areas are correctly associated to meaningful latent semantic structure in the generated captions.
