Remember When It Matters: Proactive Memory Agent for Long-Horizon Agents

Yifan Wu, Lizhu Zhang, Yuhang Zhou +5

In long-horizon tasks, decision-relevant state is often scattered across an expanding trajectory, while the action agent must surface it and act. As trajectories grow, task require…

SAGE-OPD: Selective Agent-Guided Intervention for Multi-Turn On-Policy Distillation

Yuhang Zhou, Lizhu Zhang, Yifan Wu +5

On-policy distillation (OPD) improves student models by training them on trajectories induced by their own policy, making it a promising approach for mitigating exposure bias in ag…

OmniOPD: Logit-Free On-Policy Distillation via Speculative Verification

Yuhang Zhou, Lizhu Zhang, Yifan Wu +5

On-Policy Distillation (OPD) trains a student model on its own generative trajectories under dense token-level feedback from a stronger teacher, mitigating both the off-policy dist…

Multi-Token Residual Prediction

Yufeng Xu, Zishuo Bao, Qian Wang +6

Diffusion Language Models (DLMs) generate text by iteratively denoising masked token sequences, offering a tradeoff between parallelism and quality compared to autoregressive model…

AgenticTagger: Structured Item Representation for Recommendation with LLM Agents

Zhouhang Xie, Bo Peng, Zhankui He +11

High-quality representations are a core requirement for effective recommendation. In this work, we study the problem of LLM-based descriptor generation, i.e., keyphrase-like natura…

PACEvolve: Enabling Long-Horizon Progress-Aware Consistent Evolution

Minghao Yan, Bo Peng, Benjamin Coleman +13

Large Language Models (LLMs) have emerged as powerful operators for evolutionary search, yet the design of efficient search scaffolds remains ad hoc. While promising, current LLM-i…
