Abstract:

For decades, we are interested in detecting objects and classifying them into a fixed vocabulary of lexicon. With the maturity of these low-level vision solutions, we are hunger for a higher-level representation of the visual data, so as to extract visual knowledge rather than merely bags of visual entities, allowing machines to reason about human-level decision-making. In particular, we wish an ``X’’ reasoning, where X means eXplainable and eXplicit. In this talk, I will first review a brief history of today’s prevailing visual detection methods that underpin most today’s multimedia frameworks. Then, I will introduce more challenging vision-language tasks such as visual relationship detections, natural language grounding, and image captioning. Finally, I will share my recent vision in visual reasoning by using visual knowledge graph to break current black-box deep learning models for the above multimodal tasks, especially those require reasoning such as visual Q&A and visual dialog. Through my talk, I hope that we are more ambitious to advance to the new era of multimedia research: knowledge representation + reasoning = AI.
