Augmenting Molecular Language Models with Local $n$-gram Memory

Problem Transformer-based language models applied to SMILES (Simplified Molecular Input Line Entry System) strings encounter a locality gap due to standard character-level tokenization. This fragmentation disrupts the representation of chemically…

Attention by Synchronization in Coupled Oscillator Networks

Problem The paper addresses the limitations of traditional softmax attention mechanisms in energy-constrained environments, particularly on von Neumann hardware. Softmax requires exponentiation and global reduction, which are computationally expensive and…

Runtime Enforcement of Hybrid System Properties

Problem The paper addresses the limitations of existing runtime enforcement frameworks that primarily focus on untimed or discrete-time specifications, which are inadequate for reactive systems with complex continuous dynamics. The…

PAWS: Preference Learning with Advantage-Weighted Segments

Problem The paper addresses a significant gap in preference-based reinforcement learning (PbRL) methodologies, particularly the mismatch between utility function training and policy optimization. Existing PbRL approaches typically rely on per-step…
