Structuring Semantic Embeddings for Principle Evaluation: A Prototype-Guided Contrastive Learning Approach

Che Shen, Junwei Su, Lingpeng Kong +1

Reliable post-hoc evaluation asks whether already generated text satisfies a target criterion after generation. In this paper we study a focused frozen-embedding setting using prin…

ToolSelf: Unifying Task Execution and Self-Reconfiguration via Tool-Driven Emergent Adaptation

Jingqi Zhou, Sheng Wang, Dezhao Deng +9

LLM-powered agentic systems excel at complex long-horizon tasks, but remain constrained by static configurations fixed before execution. Such rigidity forces a trade-off between do…
