MICE: Minimal Interaction Cross-Encoders for efficient Re-ranking

Mathias Vast, Victor Morand, Josiane Mothe +1

In Information Retrieval (IR), cross-encoders deliver state-of-the-art ranking effectiveness but have a high inference cost, limiting their use to second-stage re-rankers. Prior wo…

Understanding Matching Mechanisms in Cross-Encoders

Mathias Vast, Basile Van Cooten, Laure Soulier +1

Neural IR architectures, particularly cross-encoders, are highly effective models whose internal mechanisms are mostly unknown. Most works trying to explain their behavior focused…

Which Neurons Matter in IR? Applying Integrated Gradients-based Methods to Understand Cross-Encoders

Mathias Vast, Basile Van Cooten, Laure Soulier +1

With the recent addition of Retrieval-Augmented Generation (RAG), the scope and importance of Information Retrieval (IR) has expanded. As a result, the importance of a deeper under…

Navigating Uncertainty: Optimizing API Dependency for Hallucination Reduction in Closed-Book Question Answering

Pierre Erbacher, Louis Falissar, Vincent Guigue +1

While Large Language Models (LLM) are able to accumulate and restore knowledge, they are still prone to hallucination. Especially when faced with factual questions, LLM cannot only…

Simple Domain Adaptation for Sparse Retrievers

Mathias Vast, Yuxuan Zong, Basile Van Cooten +2

In Information Retrieval, and more generally in Natural Language Processing, adapting models to specific domains is conducted through fine-tuning. Despite the successes achieved by…

Augmenting Ad-Hoc IR Dataset for Interactive Conversational Search

Pierre Erbacher, Jian-Yun Nie, Philippe Preux +1

A peculiarity of conversational search systems is that they involve mixed-initiatives such as system-generated query clarifying questions. Evaluating those systems at a large scale…

Improving generalization in large language models by learning prefix subspaces

Louis Falissard, Vincent Guigue, Laure Soulier

This article focuses on large language models (LLMs) fine-tuning in the scarce data regime (also known as the "few-shot" learning setting). We propose a method to increase the gene…
