When Teachers Mislead: Spurious-Signal-Aware On-Policy Distillation

SA-OPD is proposed, a Spurious-Signal-Aware On-Policy Distillation framework that identifies and filters misleading token-level supervision based on input-groundedness and optimization impact, and consistently outperforms Vanilla OPD and competitive selective methods.

Distribution-Value Coevolution for Adaptive RLHF Data Scheduling

This work identifies and formalizes the Distribution-Value Coevolution principle: the training value of data is not intrinsic, but emerges dynamically from the interaction between data characteristics and the model's evolving capability boundary, and operationalizes this principle through a unified framework.

EM^2Mem: Event-Centric Multimodal Memory for Large Language Models

EM^2Mem is proposed, an event-centric multimodal memory framework that binds heterogeneous evidence to event anchors during memory construction, enabling compact evidence readout over grounded multimodal events rather than modality-specific fragments.

Towards principled knowledge editing methods for large language model reasoning

It is argued that effective knowledge editing must account for the intricate nature of knowledge representation, and three promising research directions are proposed that respect the complexity of knowledge representation in a real-world setting.

OneDayAgent: Towards a Long-Horizon Harness for Autonomous Agents

The same harness runs across five backend LLMs from three model families, indicating the harness generalizes across backends without tuning, even as different models induce distinct execution styles under the same workflow.

Distribution-Value Coevolution for Adaptive RLHF Data Scheduling

Reinforcement learning from human feedback (RLHF) has become the cornerstone of aligning large language models (LLMs) with human intent. Yet a fundamental question remains unaddressed: how should training data be scheduled when both the model's capabilities and the utility of data are constantly evolving? Current pipel...
