Prof. Chua Tat-Seng

Prof. Chua is the KITHCT Chair Professor at the School of Computing, National University of Singapore (NUS). He is also the Distinguished Visiting Professor of Tsinghua University and the Visiting Pao Yue-Kong Chair Professor of Zhejiang University. Dr. Chua was the Founding Dean of the School of Computing from 1998-2000. His main research interests include unstructured data analytics, video analytics, conversational search and recommendation, and robust and trustable AI. Dr. Chua is the co-Director of NExT, a joint research Center between NUS and Tsinghua, and Sea-NExT, a joint Lab between Sea Group and NExT. Dr. Chua is the recipient of the 2015 ACM SIGMM Achievements Award for the Outstanding Technical Contributions to Multimedia Computing, Communications and Applications. He is the Chair of steering committee of Multimedia Modeling (MMM) conference series, and ACM International Conference on Multimedia Retrieval (ICMR) (2015-2018). He was the General Co-Chair of ACM Multimedia 2005, ACM CIVR (now ACM ICMR) 2005, ACM SIGIR 2008, ACM Web Science 2015, ACM MM-Asia 2020, and the upcoming ACM conferences on WSDM 2023 and TheWebConf 2024. He serves in the editorial boards of three international journals. Dr. Chua is the co-Founder of two technology startup companies in Singapore. He holds a PhD from the University of Leeds, UK.


Title: Challenges in Multimodal Conversational Search and Recommendation


Abstract: Information search has been evolving from mostly unidirectional and text-based to interactive and multimodal. Recently, there is also a growing interest in all matters conversational. Multimodal conversation offers users a natural way to query the system by combining text/speech, images/videos and possibly gesture. It also helps to tackle the basic asymmetric problems by injecting conversation to help resolve the ambiguities in search and recommendation. However, the evolution from traditional IR to multimodal conversational search and recommendation (MCSR) faces many challenges. The first set of challenges touches on the basic MCSR models, including how to integrate task-oriented and open domain models, how to model multimodal context and history, and how to integrate domain knowledge and user models. The second set of challenges involves basic interactivity issues, including how to naturally converse using text and visual modalities, how to incorporate intervention strategy into search and browsing; and how to perform interactive IR, QA and recommendation. The third set of challenges looks more into the future on how to build dialogue simulator, and how to make MCSR systems extendable and active by allowing the system and users to co-evolve and becoming more intelligent together. This talk presents current research with pointers towards future research.

Title: Automated Machine Learning on Graphs


Abstract: Automated machine learning (AutoML) on graphs, which combines the strength of graph machine learning and AutoML, is gaining attentions from the research community. This talk will first overview graph machine learning and AutoML on graphs. Then, recent advances, including efficient neural architecture search for self-attention representation, hyper-parameter optimization on large-scale graphs, and increasing explainability in AutoML on graphs, will be discussed. We will also introduce AutoGL, the first dedicated framework and open-source library for AutoML on graphs, which is expected to facilitate the research and application in the community. Last but not least, we discuss multimedia applications of automated graph machine learning and share our insights on future research directions with the audience.

Title: Making the Invisible Visible: Toward High-Quality Deep THz Computational Imaging


Abstract: Terahertz (THz) computational imaging has recently attracted significant attention thanks to its non-invasive, non-destructive, non-ionizing, material-classification, and ultra-fast nature for 3D object exploration and inspection. However, its strong water absorption nature and low noise tolerance lead to undesired blurs and distortions of reconstructed THz images. The performances of existing methods are highly constrained by the diffraction-limited THz signals. In this talk, we will introduce the characteristics of THz imaging and its applications. We will also show how to break the limitations of THz imaging with the aid of complementary information between the THz amplitude and phase images sampled at prominent frequencies (i.e., the water absorption profile of THz signal) for THz image restoration. To this end, we propose a novel physics-guided deep neural network design, namely Subspace-Attention-guided Restoration Network (SARNet), that fuses such multi-spectral features of THz images for effective restoration. Furthermore, we experimentally construct an ultra-fast THz time-domain spectroscopy system covering a broad frequency range from 0.1 THz to 4 THz for building up temporal/spectral/spatial/phase/material THz database of hidden 3D objects.
