Unraveling Arithmetic in Large Language Models: The Role of Algebraic Structures

no code implementations25 Nov 2024 Fu-Chieh Chang, Pei-Yuan Wu

In this work, we propose that LLMs learn arithmetic by capturing algebraic structures, such as \emph{Commutativity} and \emph{Identity} properties.

RAD-Bench: Evaluating Large Language Models Capabilities in Retrieval Augmented Dialogues

1 code implementation19 Sep 2024 Tzu-Lin Kuo, Feng-Ting Liao, Mu-Wei Hsieh, Fu-Chieh Chang, Po-chun Hsu, Da-Shan Shiu

In real-world applications with Large Language Models (LLMs), external retrieval mechanisms - such as Search-Augmented Generation (SAG), tool utilization, and Retrieval-Augmented Generation (RAG) - are often employed to enhance the quality of augmented generations in dialogues.
