AREX: Towards a Recursively Self-Improving Agent for Deep Research

👍 116

07/23 08:00

Visual Contrastive Self-Distillation

👍 39

07/23 08:00

On-policy self-distillation (OPSD) is promising as it removes the external teacher required by on-policy distillation (OPD), yet it still needs asymmetric information between teacher and student to ensure that the self-teacher provides a stronger learning signal than the student. Existing methods cr

An Exam for Active Observers

👍 24

07/17 08:00

LLMs Get Lost in Evolving User Intent

👍 15

07/22 08:00

As LLMs become more capable, they are increasingly deployed as collaborative agents, taking on user-delegated tasks through iterative interaction. Yet genuine interaction is inherently dynamic: users rarely specify their intent upfront, instead disclosing, revising, and reshaping it as the conversat

中文介绍 揭示LLM在协作中难以跟踪用户意图的动态演变：用户常不一次性说明意图，而是在对话中披露、修订和重塑，导致模型表现下降。

Self-Supervised Learning of Structured Dynamics from Videos

👍 14

07/23 08:00

Predictive Divergence Masks for LLM RL

👍 8

07/12 08:00

Reinforcement learning for large language models (LLMs) typically relies on trust-region masks to stabilize off-policy updates.
