The Value of Mechanistic Priors in Sequential Decision Making

It is shown that priors sensitive to distribution shift can lose half of their mechanistic information under a small distribution shift, motivating physically grounded priors for safety-critical applications.

VLM-Guided Experience Replay

Across scenarios, including game-playing and robotics, spanning both discrete and continuous domains, agents trained with the proposed prioritization method achieve 15-57% higher average success rates and improve sample efficiency by 35-55% compared to previous approaches.

COMPASS: Ordered Clustered Routing at 100K Scale

The COMPASS algorithm for OCTSP is introduced, which combines search with learning-accelerated routing by orchestrating parallel sub-solvers and can reach exact solutions in time exponential in cluster size rather than instance size.

Reinforcement learning for initializing genetic algorithms in vehicle routing

This work introduces an optimization framework where a reinforcement learning agent is trained on prior instances and quickly generates initial solutions, which are then further optimized by a genetic algorithm, enabling real-time and interactive routing at scale.

Score the Algebra, Not the Span: Dimension Reduction for Transfer Operator Models of Dynamical Systems

Dimension reduction for dynamical systems is standard practice, and the standard route is spectral: model the transfer (Koopman) operator by its leading modes. We show that on systems assembled from several weakly interacting components --- a structure common in physical and biological settings --- this may either requ...
