When Do Concepts Become Functionally Sufficient During Language-Model Training?

Raphael Bernas, Paul G. Chevalier, Fanny Jourdan +1

Understanding a model and its learning mechanisms in depth requires identifying when its internal structures become useful, rather than simply looking at the final state. We study…

Revisiting Anisotropy in Language Transformers: The Geometry of Learning Dynamics

Raphael Bernas, Fanny Jourdan, Antonin Poché +1

Since their introduction, Transformer architectures have dominated Natural Language Processing (NLP). However, recent research has highlighted an inherent anisotropy phenomenon in…

ConSim: Measuring Concept-Based Explanations' Effectiveness with Automated Simulatability

Antonin Poché, Alon Jacovi, Agustin Martin Picard +2

Concept-based explanations work by mapping complex model computations to human-understandable concepts. Evaluating such explanations is very difficult, as it includes not only the…

FairTranslate: An English-French Dataset for Gender Bias Evaluation in Machine Translation by Overcoming Gender Binarity

Fanny Jourdan, Yannick Chevalier, Cécile Favre

Large Language Models (LLMs) are increasingly leveraged for translation tasks but often fall short when translating inclusive language -- such as texts containing the singular 'the…
