Simulation-Free PSRO: Removing Game Simulation from Policy Space Response Oracles

Yingzhuo Liu, Shuodi Liu, Weijun Luo +2

Policy Space Response Oracles (PSRO) combines game-theoretic equilibrium computation with learning and is effective in approximating Nash Equilibrium in zero-sum games. However, th…

Unlocking the Address Book: Dissecting the Sparse Semantic Structure of LLM Key-Value Caches via Sparse Autoencoders

Qingsen Ma, Dianyun Wang, Jiaming Lyu +8

The Key-Value (KV) cache is the primary memory bottleneck in long-context Large Language Models, yet it is typically treated as an opaque numerical tensor. In this work, we propose…
