DEO: Training-Free Direct Embedding Optimization for Negation-Aware Retrieval

Taegyeong Lee, Jiwon Park, Seunghyun Hwang +1

Recent advances in Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG) have enabled diverse retrieval methods. However, existing retrieval methods often fail to a…

Relevance to Utility: Process-Supervised Rewrite for RAG

Jaeyoung Kim, Jongho Kim, Seung-won Hwang +2

Retrieval-augmented generation systems often suffer from a gap between optimizing retrieval relevance and generative utility. With such a gap, retrieved documents may be topically…

Intended Target Identification for Anomia Patients with Gradient-based Selective Augmentation

Jongho Kim, Romain Storaï, Seung-won Hwang

In this study, we investigate the potential of language models (LMs) in aiding patients experiencing anomia, a difficulty identifying the names of items. Identifying the intended t…

Counterfactual-Consistency Prompting for Relative Temporal Understanding in Large Language Models

Jongho Kim, Seung-won Hwang

Despite the advanced capabilities of large language models (LLMs), their temporal reasoning ability remains underdeveloped. Prior works have highlighted this limitation, particular…
