How RL Reshapes LLM Reasoning: Transferability, Coverage, and Scaling Laws

Recent studies on reinforcement learning (RL) report seemingly conflicting evidence about large language model (LLM) reasoning. Training on mathematics can improve performance in other domains, yet gains in Pass@1 can coincide with lower Pass@$N$ than the base model. This raises a fundamental question: does RL expand a...

Compact Heterodyne Pinhole Point-Diffraction Interferometer with High Repeatability and Adjustable Contrast Based on Dual-Cascaded Acousto-Optic Modulators

Conventional pinhole point-diffraction interferometers (PPDIs) owe their popularity to a simple configuration, but that same configuration limits both the usable measurement aperture and the load the phase shifter can carry. Here, we propose a heterodyne phase-shifting point-diffraction interferometer (HPDI) based on d...

Safe Learning Under Irreversible Dynamics via Asking for Help

This work provides an algorithm whose regret and number of mentor queries are both sublinear in the time horizon for Markov decision processes with irreversible dynamics and infinite state spaces and shows that this combination enables the agent to learn both safely and effectively.
