Fine-Grained Bidirectional Attention-Based Generative Networks for Image-Text Matching.

In this paper, we propose a method called BiKA (Bidirectional Knowledge-assisted embedding and Attention-based generation) for the task of image-text matching. It mainly improves the embedding ability of images and texts from two aspects: first, modality conversion, we build a bidirectional image and text generation network to explore the positive effect of mutual conversion between modalities on image-text feature embedding; then is relational dependency, we built a bidirectional graph convolutional neural network to establish the dependency between objects, introduce non-Euclidean data into image-text fine-grained matching to explore the positive effect of this dependency on fine-grained embedding of images and texts. Experiments on two public datasets show that the performance of our method is significantly improved compared to many state-of-the-art models.
