Quantifying Retriever-Generator Alignment in RAG with Local Explanations

Korbinian Randl, Guido Rocchietti, Aron Henriksson +3

Retrieval-Augmented Generation (RAG) systems combine dense retrievers and language models to ground their outputs in external documents. However, the interaction between these comp…

Evaluating the Reliability of Self-Explanations in Large Language Models

Korbinian Randl, John Pavlopoulos, Aron Henriksson +1

This paper investigates the reliability of explanations generated by large language models (LLMs) when prompted to explain their previous output. We evaluate two kinds of such self…
