Sparse Prefix Caching for Hybrid and Recurrent LLM Serving

Researchers propose sparse prefix caching, a novel optimization technique for hybrid and recurrent LLM serving that stores exact states at checkpoint positions rather than caching entire token histories. The method uses dynamic programming to determine optimal checkpoint placement and demonstrates superior performance on real-world datasets while using fewer checkpoints than existing dense caching approaches.

Completion vs Optimality: Policy Gradient in Long-Horizon Cumulative-Damage Problems

Researchers identify critical failure modes in policy-gradient reinforcement learning methods when applied to long-horizon problems with cumulative damage, where short-term attractive actions lead to long-term negative outcomes. The study proposes a decomposition framework separating completion (reaching terminal horizon) from optimality (achieving dynamic-programming benchmarks) and validates predictions across two distinct domains: career planning and sports performance.

StructRL: Recovering Dynamic Programming Structure from Learning Dynamics in Distributional Reinforcement Learning

StructRL is a new reinforcement learning framework that recovers dynamic programming structure from distributional learning dynamics without requiring explicit models. The research demonstrates that temporal patterns in return distribution evolution reveal inherent structure in how information propagates through state spaces, enabling more efficient and stable learning.
