Papers
- RM-R1: Reward Modeling as Reasoning (2025 · 49 citations)
Reward models guide the alignment of LLMs, but each existing family has a weakness. Scalar RMs give no justification for their scores. Generative RMs explain their verdicts, yet their reasoning is often shallow. The authors treat preference judgment as a reasoning problem and introduce Reasoning Reward Models… - MEMORYLLM: Towards Self-Updatable Large Language Models (2024 · 27 citations)
Large language models are usually frozen once deployed, which makes adding fresh knowledge difficult. Current workarounds each have drawbacks. Retrieval stores keep growing, fact-level editing struggles with longer passages, and long-context approaches eventually run out of context length. This paper proposes… - Current Agents Fail to Leverage World Model as Tool for Foresight (2026 · 1 citation)
The paper asks whether today's vision-language agents can treat a generative world model as an optional external tool: a simulator they consult to preview the consequences of an action before committing to it in the real environment. - Beyond Sample-Level Feedback: Using Reference-Level Feedback to Guide Data Synthesis (2026)
Synthetic instruction-tuning data is cheap to produce, but a model trained on it usually cannot exceed the LLM that generated it.
