EvoHarness-RL: Learning Self-Evolving Runtime Harness for Long-Horizon LLM Agents

Xuying Ning, Dongqi Fu, Tianxin Wei +13

Long-horizon LLM agents increasingly rely on external execution support to maintain state, track progress, invoke tools, verify outcomes, and reuse experience across interactions.…

KVEraser: Learning to Steer KV Cache for Efficient Localized Context Erasing

Mufei Li, Shikun Liu, Dongqi Fu +5

Post-hoc context erasing over the KV cache is challenging because a local edit has a global consequence: once a span has been processed, its influence propagates into the cached st…

Structuring and Tokenizing Distributed User Interest Context for Generative Recommendation

Ruizhong Qiu, Yinglong Xia, Dongqi Fu +6

Generative recommendation is an emerging paradigm that has shown promise in industrial recommendation systems, aiming to predict users' next interactions from their historical beha…

Protein Representation Learning with Secondary-Structure and Energy-Filtered Hydrogen-Bond Graphs

Mohamed Mouhajir, Limei Wang, El Houcine Bergou +3

Graph-based representations are widely used in protein modeling, yet many existing approaches rely primarily on sequence adjacency or geometric proximity, which only partially refl…

Towards Direct Latent-Space Synthesis for Parallel Branches in LLM-Agent Workflows

Shikun Liu, Mufei Li, Dongqi Fu +5

Large language models increasingly serve as execution engines for agentic systems, yet they still consume context through a sequential text interface. This creates a mismatch with…

ChronoID: Infusing Explicit Temporal Signals into Semantic IDs for Generative Recommendation

Dongdong Nian, Dongqi Fu, Chenliang Xu +4

Semantic IDs are crucial in generative recommendation, but with a fundamental limitation: temporal information is not well incorporated into semantic IDs. Instead, time influences…
