Verifying Chain-of-Thought Reasoning via Its Computational Graph Verifying Chain-of-Thought Reasoning via Its Computational GraphCurrent Chain-of-Thought (CoT) verification methods predict reasoning correctness based on outputs (black-box) or activations (gray-box), but offer limited insight into why a computation fails. We introduce a white-box method: Circuit-based Reasoning Verification (CRV). We hypothesize that attribution

안녕하세요 GUG입니다. 어느덧 내일 GUG 7번째 세미나가 진행됩니다. 5회차 세미나부터 늘 '온톨로지' 라는 키워드를 가지고 세미나를 진행했는데, 유독 이번 세미나는 관심과 신청이 더 많았던게 느껴졌네요. 아마 팔란티어 기업의 활약이 주된 이유이지 않을까 싶네요. 좋은 현상이라 생각합니다. 그래프란 분야가 온톨로지 덕분에 빛을 발하는 시기가 되는거 같아 더더욱 열심히 하게되는
