Ego2World: Compiling Egocentric Cooking Videos into Executable Worlds for Belief-State Planning
Qinchuan Cheng, Zhantao Gong, Pengzhan Sun +2
Egocentric videos capture how people carry out everyday activities, yet testing an agent requires evaluating the consequences of actions it chooses itself. We introduce Ego2World,…
EgoVine: Post-Training with Branching Experience Compiled from Real-World Videos
Qinchuan Cheng, Bowen Lyu, Zhantao Gong +3
Real-world egocentric videos capture multi-step household procedures, but their recorded trajectories leave alternative actions and recovery from the learner's own mistakes largely…
Target-Dependent Limits of Causal Repair: A Leading-Log Frontier in a Gaussian Model
Qinchuan Cheng, Jiaqi Liu, Ruixuan Xie
Knowing how much a causal predictor could improve need not reveal the gain of the repair actually learned. We quantify this gap in a scalar Gaussian causal experiment with known in…
Reserve-Aware Contrast Certificates for Conservative Bandits with Uncertain Baselines
Qinchuan Cheng
Conservative bandits must improve an incumbent policy without exhausting a prescribed performance budget. When the incumbent is uncertain, separately bounding candidate and baselin…
MAP-Law: Coverage-Driven Retrieval Control for Multi-Turn Legal Consultation
Qinchuan Cheng, Jiaqi Liu, Ruixuan Xie +2
Legal consultation is inherently iterative: before giving advice, a system must identify relevant legal elements, gather missing facts and authorities, and determine whether the cu…

Qinchuan Cheng, Zhantao Gong, Pengzhan Sun +3
Embodied agents in household environments must plan under partial observation: they need to remember objects, track state changes, and recover when actions fail. Existing benchmark…
