Rebalancing Return Coverage for Conditional Sequence Modeling in Offline Reinforcement Learning

NeurIPS 2025poster

Recent advancements in offline reinforcement learning (RL) have underscored the capabilities of conditional sequence modeling (CSM), a paradigm that models the action distribution conditioned on both historical trajectories and target returns associated with each state. However, due to the imbalance…

AttentionLUT: Attention Fusion-Based Canonical Polyadic LUT for Real-Time Image Enhancement

ICASSP 2024accepted

Recently, many algorithms have employed image-adaptive lookup tables (LUTs) to achieve real-time image enhancement. Nonetheless, a prevailing trend among existing methods has been the employment of linear combinations of basic LUTs to formulate image-adaptive LUTs, which limits the generalization ab…
