Demonstration Synthesis from a Single Scan via Gaussian Splatting for Visuomotor Policy Learning
Beichen Wang, Yuen-Hei Yeung, V. R. Sridhar Devarakonda +1
Training a visuomotor policy calls for abundant demonstrations that closely match the target environment, yet collecting them anew remains expensive. Existing demonstration synthes…
Learning Scene-Aware Humanoid Locomotion through 3D Clutter from Immersive Human Demonstrations
Beichen Wang, Tong Xu, Daniel Kosukhin +3
While learning from human motions has enabled highly dynamic humanoid skills such as dancing and martial arts in obstacle-free space, traversal through densely cluttered environmen…
Resist, Update, Reject: Preference Optimization Installs a Prior-Dependent Reliability Switch
Sen Yang, Yuen-Hei Yeung
An aligned model asked to hold its answer against a manipulative source must still update on a reliable one and reject an unreliable one: resistance, reliable-update, and unreliabl…
Unlearning as Distribution Restoration: A Controlled Counterfactual Study, a Validated Selective Screen, and the Limits of Oracle-Free Certification
Sen Yang, Yuen-Hei Yeung
Machine unlearning is commonly evaluated by matching a retrained oracle on trained probes. In a controlled nonce-fact testbed with a matched retraining reference, we find this crit…
Resist and Update: Counterfactual Report Coordinates for Incentive-Compatible LLMs
Sen Yang, Yuen-Hei Yeung
Aligned language models routinely misreport under non-evidential pressure: they cave to a confident user, yet fail to revise when genuine evidence arrives. We cast this as a failur…
Leveraging RGB-D Data with Cross-Modal Context Mining for Glass Surface Detection
Jiaying Lin, Yuen-Hei Yeung, Shuquan Ye +1
Glass surfaces are becoming increasingly ubiquitous as modern buildings tend to use a lot of glass panels. This, however, poses substantial challenges to the operations of autonomo…
