My research interests include computer vision and machine learning, where I lead a young and energetic research team that has published more than 100 papers in related top peer-review conferences and journals (e.g. CVPR, NeurIPS, TPAMI, TIP etc). I was the founding Chair for IEEE Computational Intelligence Society, Malaysia chapter.
Also currently, I serve as the Associate Editor of Pattern Recognition (Elsevier), and have co-organized several conferences/workshops/tutorials/challenges related to computer vision/machine learning. I was the recipient of Malaysia Scopus Research Excellence Awards (Research Innovations) in 2024, Top Research Scientists Malaysia (TRSM) in 2022, Young Scientists Network Academy of Sciences Malaysia (YSN-ASM) in 2015 and Hitachi Research Fellowship in 2013. Besides that, I am also a senior member (IEEE), Professional Engineer (BEM) and Chartered Engineer (IET).
During 2020-2022, I was seconded to the Ministry of Science, Technology and Innovation (MOSTI) as the Undersecretary for Division of Data Strategic and Foresight.

OneHOI: Unifying Human-Object Interaction Generation and Editing Star
J.T. Hoe, W. Hu, X. Jiang, Y-P. Tan and C.S. Chan
CVPR 2026 (main, acceptance rate: 4090/16,092 ~ 25.42%)
Rather than treating generation and editing as separate problems, this paper - OneHOI models both as a unified conditional denoising process grounded in structured ⟨person, action, object⟩ relations, enabling (i) Single-interaction generation; (ii) Identity-preserving editing, and (iii) Multi-HOI editing. All within one coherent framework.
pdf (coming soon) Project Page codeTowards Privacy-Guaranteed Label Unlearning in Vertical Federated Learning: Few-Shot Forgetting without Disclosure Star
H. Gu, H.X. Tae, L. Fan and C.S. Chan
ICLR 2026 (acceptance rate: 5339/18,949 ~ 28.18%)
We address label unlearning in Vertical Federated Learning (VFL), where labels are essential for training yet also privacy-sensitive. Our approach uses representation-level manifold mixup to generate synthetic embeddings for both forgotten and retained samples, enabling more effective and efficient gradient-based forgetting while preserving model performance
pdf (OpenReview) codeGorgeous: Creating narrative-driven makeup ideas via image prompts Star
J.W. Sii and C.S. Chan
Multimedia Tools and Applications (2025)
Gorgeous is a diffusion-based makeup generator that turns any image prompt (like fire or moonlight) into creative, narrative-driven makeup on a face, rather than simply copying an existing style. From inspiration to personalized beauty in seconds to unlock scalable, AI-powered creativity for brands, artists, and consumers.
pdf codeMaverick: Collaboration-free Federated Unlearning for Medical Privacy Star
W.K. Ong and C.S. Chan
MICCAI 2025 (oral, acceptance rate: 76/3447 ~ 2.2%)
We propose Maverick, the first Collaboration-free Federated Unlearning framework, enabling unlearning based on a single client’s request for medical applications. That is, as soon as a client requests data removal, our method can act independently, eliminating the need for global collaboration from other clients
