SoCRATES: Towards Reliable Automated Evaluation of Proactive LLM Mediation across Domains and Socio-cognitive Variations

Taewon Yun, Hyeonseong Park, Jeonghwan Choi +3

Evaluating LLM mediators remains challenging, as mediation unfolds as a real-time trajectory shaped by disputants' shifting emotions, intentions, and context. Existing testbeds rel…

Distilling Long-CoT Reasoning through Collaborative Step-wise Multi-Teacher Decoding

Taewon Yun, Jisu Shin, Jeonghwan Choi +2

Distilling large reasoning models is essential for making Long-CoT reasoning practical, as full-scale inference remains computationally prohibitive. Existing curation-based approac…

Completing Missing Annotation: Multi-Agent Debate for Accurate and Scalable Relevant Assessment for IR Benchmarks

Minjeong Ban, Jeonghwan Choi, Hyangsuk Min +4

Information retrieval (IR) evaluation remains challenging due to incomplete IR benchmark datasets that contain unlabeled relevant chunks. While LLMs and LLM-human hybrid strategies…

Aligning Extraction and Generation for Robust Retrieval-Augmented Generation

Hwanjun Song, Jeonghwan Choi, Minseok Kim

Retrieval-augmented generation (RAG) enhances LLMs with external knowledge, yet generation remains vulnerable to retrieval-induced noise and uncertain placement of relevant chunks,…
