ABSTRACT:

Cross-modal learning for images and language is vital to solving many AI applications including image-text retrieval, visual grounding, image captioning and so on. In this talk, I will first introduce our two-branch neural networks for matching images and language in the joint space. I will demonstrate this framework is highly flexible to adapt to various AI tasks.  Second, I will present our recent works of deep generative models that can generate human-like language descriptions. Our approaches can not only generate diverse descriptions conditioned on the image input, but also improve the accuracy of the generation results. Finally, I will introduce my recent efforts in improving traditional AI tasks like captioning and ranking with reinforcement learning.
