ProAR: Learning Prospective Reasoning with Autoregressive Video Models
Turning reactive autoregressive video generation into a prospective reasoning process through goal-frame anchoring and future representation self-alignment.
Linghui Shen
Hi there👋! I am Linghui Shen (沈凌卉), a fourth-year undergraduate student in Computer Science at The Hong Kong Polytechnic University, with a minor in
Applied Mathematics. I also spent a wonderful semester at KTH Royal Institute of Technology in Sweden as an exchange student.
I am fortunate to be supervised by Xingyi Yang at PolyU.
I am grateful for the experience of working with Muhao Chen at UC Davis.
News
- Start a summer internship with Muhao Chen at UC Davis.
- Start my exchange semester at KTH in Stockholm, Sweden.
Research Interest
My research focuses on generative models that learn predictive representations of the physical world. I aim to advance visual intelligence by enabling these models to anticipate, reason about, and simulate dynamic environments reliably and efficiently. I am extending my research toward representation learning and embodied AI.
BadWorld: Adversarial Attacks on World Models
Combining velocity attacks and trajectory-adaptive optimization to craft imperceptible image perturbations that disrupt interactive world-model rollouts across unseen controls, without ground-truth future videos.
SAE Interventions are Unreliable: Post-Intervention Recovery of Suppressed Behavior
Suppressed model behavior can recover while targeted SAE features remain clamped, exposing a gap between feature control and behavioral safety.
DeContext as Defense: Safe Image Editing in Diffusion Transformers
The first defense framework against unauthorized DiT-based in-context image editing, using imperceptible perturbations to disrupt cross-attention while preserving visual quality.
Provably Robust Adaptation for Language-Empowered Foundation Models
Certifying few-shot classifiers built on language-empowered foundation models against support-set poisoning attacks.
