📌 Research Interests

My research focuses on building embodied agents that can perceive, remember, reason, and act in dynamic physical environments, including: (i) VLM-based robotic agents with persistent spatio-temporal memory for long-horizon manipulation, (ii) physical-scale and streaming 4D world modeling, (iii) multimodal evaluation and enhancement for localized dynamics perception and 4D reasoning, and (iv) foundation-model-based perception under anomalous or ambiguous visual conditions. These directions connect dynamic perception, multimodal reasoning, persistent memory, and grounded action toward open-world embodied intelligence.

Preprint TAU-Bench overview connecting anomaly instance tracking with fine-grained video anomaly understanding

TAU-Bench: From Anomaly Instance Tracking to Fine-Grained Video Anomaly Understanding

Kepeng Yang*, Dongxuan Liu*, Rongxin Gao*, Zixin Su, Rui Wu, Shuzhao Xie, Chenxin Li, Panwang Pan, Yuzhi Huang†, Yue Huang†, Jingyan Jiang

Preprint, 2026

Project Page arXiv
Abstract

TAU-Bench is a track-centric benchmark for jointly evaluating anomaly instance tracking and fine-grained video anomaly understanding.

- We introduce TAU-Bench, which grounds fine-grained anomaly understanding in identity-consistent instance tracks. It comprises 1,118 videos, 1,454 anomaly tracks, and 202,438 pixel-level masks across 49 event and 45 scene categories.

Preprint ChainVLA execution-state overview for long-horizon manipulation

ChainVLA: Chaining Vision-Language-Action Queries through a Unified Execution State for Long-Horizon Manipulation

Preprint, 2026

Project Page 小红书 arXiv
Abstract

ChainVLA is a 1.2B-parameter VLA policy that connects successive action queries through a joint, revisable execution state, carrying both task progress and unfinished motion across long-horizon manipulation.

- We introduce ChainVLA, which combines Progress Context with Motion Tail to preserve observation-derived task progress and the preceding prediction's unexecuted continuation across VLA queries. ChainVLA reaches 62.8% average success on RMBench and 98.8% across four LIBERO suites.

Abstract

DynTrace is a training-free framework that tracks continuous dynamic object evidence for coherent 4D reasoning. It combines geometry-informed trajectory visualization with a structured Dynamic Trace Graph.

- We introduce DynTrace, a training-free framework that enables MLLMs to continuously track dynamic object evidence for coherent 4D spatio-temporal reasoning. It combines geometry-informed Dynamic Trajectory Visualization with a structured Dynamic Trace Graph to disentangle genuine object dynamics from camera-induced motion and preserve evolving object-level cues across time.

Abstract

RoboStream weaves spatio-temporal reasoning with persistent memory into VLM robotic planners, supporting long-horizon object grounding and causal state tracking.

- We propose RoboStream, a training-free framework that equips VLM-based robotic planners with persistent spatio-temporal memory for long-horizon manipulation. Spatio-Temporal Fusion Tokens maintain object grounding, while a Causal Spatio-Temporal Graph records action-triggered state transitions, achieving 90.5% on long-horizon RLBench and 44.4% on challenging real-world block-building tasks.

Abstract

Dyn-Bench evaluates whether MLLMs can perceive, track, and reason about evolving 4D scenes using 1K videos, 7K VQA pairs, and 3K dynamic-object grounding pairs.

- We introduce Dyn-Bench, a large-scale benchmark for systematically evaluating how MLLMs perceive, track, and reason about dynamics in the physical 4D world. It contains 1K diverse videos, 7K visual question-answering pairs, and 3K dynamic-object grounding pairs, revealing that existing models struggle to maintain both strong spatio-temporal reasoning and precise localized grounding. We further study structured integration strategies, including Mask-Guided Fusion and Spatio-Temporal Textual Cognitive Maps, to improve dynamic-world understanding.
