Associate Professor · Université Paris-Saclay · LISN

My work focuses on adaptive and resource-efficient machine learning. I study learning systems that must adapt to evolving data while operating under constraints on memory, data, and computation.

I am an Assistant Professor (Maîtresse de conférences en informatique) at Université Paris-Saclay. I am a member of the LISN laboratory, and I teach at the UFR des Sciences d'Orsay.

Research programme

Adaptive and resource-efficient machine learning

My research combines continual learning and efficient representation architectures, with applications across vision, speech, language, and scientific machine learning.

Continual learning

Approach

Analyse and recommend continual learning methods, in particular class-incremental learning methods, taking into account model initialization, representation transfer, and memory constraints.

Research question

How should an incremental learner update its representation when earlier examples cannot be retained? Which hypotheses can we make on the future data stream and how to use them for current updates? How to evaluate continual learning models?

Selected publications

Reality Check on Pre-training
Temporal Dynamics in Visual Data
AdvisIL

Efficient representation architectures

Approach

Design better neural architectures with inductive biases suited to the data of interest. Study alternatives to standard attention and mixing mechanisms, for vision, audio, or physical data.

Research question

How to incorporate domain-specific inductive bias in existing neural architectures (Transformer, FNO...)? Does it improve model expressivity, or sample efficiency? In particular, which architectural mechanisms preserve useful global interactions while reducing memory or computational costs in speech, vision, and operator learning?

Selected publications

Polynomial Mixing for Speech Encoders
Multipole Attention

Multimodal learning

Perspectives

Connect continual learning with multimodal systems, particularly vision–language models and speech-to-text models. I also like applying my work to the analysis and curation of cultural or historical artifacts.

Polynomial Mixing for Efficient Self-supervised Speech Encoders

We propose a polynomial token mixer as a drop-in alternative to multi-head self-attention in a self-supervised speech encoder. The proposed mixer offers a trade-off between recognition performance, runtime, and memory use.

Linear Attention with Global Context: A Multipole Attention Mechanism for Vision and Physics

We propose MANO, a linear-attention mechanism intended to retain global contextual interactions while limiting the cost associated with standard attention. MANO shows competitive performance in image classification and physics-oriented benchmarks.

A Reality Check on Pre-training for Exemplar-free Class-Incremental Learning

This study compares several initialization and pre-training strategies across exemplar-free class-incremental learning algorithms and datasets. We analyse how the usefulness of pre-training depends on domain alignment and provide practical recommendations for designing continual learning systems.

Temporal Dynamics in Visual Data: Analyzing the Impact of Time on Classification Accuracy

We introduce VCT-107, a visual dataset organised by collection period, and analyse how classification accuracy changes when training and test data come from different periods. The results motivate explicit treatment of temporal shift and regular model updating.
