I am a Nanyang Associate Professor at the School of Computer Science and Engineering, Nanyang Technological University, Singapore. My research interests lie mainly in Computational Narrative Intelligence, Multi-modal Learning, and Machine Learning.
Story is a powerful tool for communication, an exhibit of creativity, and a timeless form of entertainment. Computational Narrative Intelligence (CNI) aims to create intelligent machines that can understand and create stories, manage interactive narratives, and respond appropriately to stories told to them. I have made contributions to all major areas of CNI, ranging from story generation and interactive narratives to human cognition, from learning story knowledge to story understanding.
CNI is obviously a hard problem, requiring semantic understanding and powerful learning algorithms. Therefore, I am also interested in methods that learn grounded, multimodal semantics and strong machine learning algorithms. In particular, I am excited by techniques that adopt a system view of intelligence, which considers the interaction of multiple specialized components.
Haoxin Li, Yuan Liu, Hanwang Zhang, and Boyang Li. Mitigating and Evaluating Static Bias of Action Representations in the Background and the Foreground. International Conference on Computer Vision (ICCV) (Oral Presentation). 2023.
TL;DR: Video classifiers often rely on static features to make biased predictions. We show that static bias is caused by not only the background, but also the foreground, such as human actor's outfit or instrument. We propose a theory-inspired method to mitigate bias without having to locate the source.Paper Supplemental Code bibtex

Anthony Meng Huat Tiong, Junnan Li, Boyang Li, Silvio Savarese, and Steven C.H. Hoi. Plug-and-Play VQA: Zero-shot VQA by Conjoining Large Pretrained Models with Zero Training. Findings of the Conference on Empirical Methods in Natural Language Processing (Findings of EMNLP). 2022.
TL;DR: An unexpected modular approach to visual question answering. We translate relevant portions of an image to text and rely on text-based reasoning entirely. On VQAv2, the results are better than Deepmind's Flamingo by 8.5%. This is in contrast to conventional wisdom that end-to-end learning is necessary for good performance.Paper Video Code bibtex
Xu Guo, Boyang Li, and Han Yu. Improving the Sample Efficiency of Prompt Tuning with Domain Adaptation. Findings of the Conference on Empirical Methods in Natural Language Processing (Findings of EMNLP). 2022.

TL;DR: If neural recommenders performed poorly (e.g., worse than well-tuned k-nearest-neighbors), it is probably because they did not use this data-dependent, manifold-informed initialization.Paper Video Code bibtex
