| Jul 09, 2026 | Our paper titled “Beyond Post-Hoc Temperature Scaling: Bilevel Optimization for LLM Calibration” has been accepted to COLM. Thanks for all the collaborators! |
| Jul 01, 2026 | I officially joined NUS SoC as an Assistant Professor. |
| Jun 24, 2026 | Our paper, Adversarial Rademacher Complexity of Deep Neural Networks, has been accepted for publication in JMLR. The paper has had a rather eventful journey. It was first submitted to ICLR 2022 and received scores of 8/8/8/6, but was not accepted. We subsequently submitted a revised version to JMLR, where the review process took longer than we had anticipated. We are very glad that the journey has now reached a positive conclusion. I am deeply grateful to everyone who supported and helped me along the way. |
