To Defer or Not to Defer? Online Learning with LLMs and Congested Experts

Modern AI systems increasingly combine large language models (LLMs) with human experts, using the LLM to handle routine queries while deferring uncertain cases for expert review. When expert capacity is limited, however, deferral decisions must account not only for the reliability of the LLM but also for congestion in...

Shift Before You Learn: Enabling Low-Rank Representations in Reinforcement Learning

This work demonstrates that a low-rank structure naturally emerges in the shifted successor measure, which captures the system dynamics after bypassing a few initial transitions, and establishes a connection between the necessary shift and the local mixing properties of the underlying dynamical system, which provides a...
