AI and Deep Learning
Scientific objectives
The theme explores the ability of deep learning to automatically extract complex representations from heterogeneous data (images, text, signals, biological data). These representations, often in the form of embeddings, make it possible to capture abstract structures useful for analysis and prediction.
Au-delà de la performance, le thème vise à développer des modèles compréhensibles et fiables. L’interprétabilité est essentielle pour garantir la confiance des utilisateurs, en particulier dans des domaines sensibles comme la santé ou l’environnement.
Ces travaux portent également sur la robustesse des modèles face à des données bruitées, incomplètes ou biaisées.
The theme addresses both discriminative approaches (classification, detection) and generative approaches (language models, image or data generation). The rise of large language models notably opens up new perspectives for natural language processing, including in low-resource contexts.
An important focus concerns the development of more resource-efficient AI models capable of operating on constrained devices (sensors, embedded systems). This objective is crucial to ensure the accessibility and sustainability of the developed solutions.
Scientific challenges
Data quality and bias
The performance of AI models strongly depends on data quality. Bias, lack of diversity, or annotation errors can significantly limit their generalization capabilities. The theme works in close connection with other axes to improve the quality and representativeness of data.
Data annotation and semi-supervised learning
Data annotation represents a major cost. The theme explores alternative approaches such as semi-supervised learning, continual learning, or human-in-the-loop methods, in order to leverage partially annotated data.
Architecture design
Designing suitable architectures remains a challenge, often addressed in an empirical and costly manner. The theme aims to better structure this design space, in particular to develop more efficient and frugal models.
Applications
Image analysis (coral reefs), processing of ecological data, development of environmental indicators.
Automatic language processing, information extraction from legal or scientific corpora.
Activities
Le thème organise et soutient une animation scientifique dynamique :
financement de projets collaboratifs,
organisation de formations et séminaires,
mise en place d’un cycle régulier de séminaires internes.
Une attention particulière est portée à l’animation d’une communauté large incluant doctorants, post-doctorants et jeunes chercheurs, afin de favoriser les échanges et la veille scientifique dans un domaine en évolution rapide.
