• Abstract: Visual-semantic embedding enables various tasks such as image-text retrieval, image captioning, and visual question answering. The key to successful visual-semantic embedding is to express visual and textual data properly by accounting for their intricate relationship. While previous studies have achieved much advance by encoding the visual and textual data into a joint space where similar concepts are closely located, they often represent data by a single vector ignoring the presence of multiple important components in an image or text. Thus, in addition to the joint embedding space, we propose a novel multi-head self-attention network to capture various components of visual and textual data by attending to important parts in data. Our approach achieves the new state-of-the-art results in image-text retrieval tasks on MS-COCO and Flicker30K datasets. Through the visualization of the attention maps that capture distinct semantic components at multiple positions in the image and the text, we demonstrate that our method achieves an effective and interpretable visual-semantic joint space.

  A critical challenge to image-text retrieval is how to learn accurate correspondences between images and texts. We propose a Scene Graph based Fusion Network (dubbed SGFN) which enhances the images'/texts' features through intra- and cross-modal fusion. Our SGFN performs better than quite a few SOTA image-text retrieval methods.

We show that the scale of our corpus can make up for its noise and leads to state-of-the-art representations even with such a simple learning scheme.
