Revealing After Overwriting: An Exponential POMDP OPE Lower Bound under History-Dependent Logging
Youyu Luo, Pengzhan Zhou, Zhida Qin +4
Multi-step revealing can make off-policy evaluation tractable under memoryless logging. With history-dependent logging, state decodability and target-relevant evidence can separate…

Adaptive Cross-Modal Fusion with Sparse Attention for Pedestrian Crossing Intention Prediction
Md Mahfuzur Rahman, Pengzhan Zhou, A F M Abdun Noor +5
Predicting pedestrian crossing intention is a safety-critical task for autonomous driving, yet existing approaches often rely on single-modal inputs or dense multimodal fusion stra…
