A propos du centre ou de la direction fonctionnelle
The Inria centre at Université Côte d'Azur includes 42 research teams and 9 support services. The centre's staff (about 500 people) is made up of scientists of dierent nationalities, engineers, technicians and administrative staff. The teams are mainly located on the university campuses of Sophia Antipolis and Nice as well as Montpellier, in close collaboration with research and higher education laboratories and establishments (Université Côte d'Azur, CNRS, INRAE, INSERM...), but also with the regiona economic players.
With a presence in the fields of computational neuroscience and biology, data science and modeling, software engineering and certification, as well as collaborative robotics, the Inria Centre at Université Côte d'Azur is a major player in terms of scientific excellence through its results and collaborations at both European and international levels.
Contexte et atouts du poste
Federated learning (FL) is a distributed machine learning approach that enables multiple clients to
collaboratively train a shared global model without exchanging their raw data, mitigating privacy
concerns and reducing communication costs. In standard FL, a single global model is learned by
aggregating locally trained updates from clients, assuming that all client data are drawn from a
similar distribution. However, in practice, client data are often highly heterogeneous-reflecting
diverse user behaviors and environments-which can lead to poor performance of the global model
on individual clients. Personalized federated learning (PFL) addresses this challenge by adapting
the global training process to account for client-specific data characteristics.
The postdoc is funded by the Inria Challenge FedMalin on federated learning and will BE based in the PREMEDICAL team.
Mission confiée
In this project, we will focus on two complementary thrusts : (1) designing metrics to quantify
statistical heterogeneity across client distributions; and (2) developing optimization and learning
algorithms that leverage these metrics to achieve provably effective personalized model training
under communication constraints.
Opportune Metrics for Statistical Heterogeneity
- Definition of Distributional Discrepancy Metrics : Develop novel measures that capture
both global and local differences in feature-label joint distributions, extending beyond
traditional divergence measures (e.g., Wasserstein, KL, MMD) to incorporate feature
relevance and task-specific losses.
- Weak-Communication Adaptation : Adapt metrics to settings with limited exchange of
summary statistics, ensuring that clients can compute and share compact heterogeneity
scores without revealing raw data.
2.2. Novel Learning Algorithms
- Personalized FL Algorithms with Optimal Client Selection : Design algorithms that use
heterogeneity-aware metrics to optimally select weighted subsets of clients for aggregation.
These methods aim to minimize gradient variance and reduce model bias by ensuring that
selected clients are both representative and informative. The approach will BE grounded in
theoretical analysis and empirically validated in federated settings.
- Communication-Efficient Protocols : Integrate sampling schemes with quantization and
compression techniques to ensure compatibility with bandwidth constraints, analyzing trade-
offs between compression error and sampling-induced variance.
To evaluate the usefulness of the proposed techniques, we will work with synthetic data and open
benchmark datasets. The research will BE made available in open access and we will seek to publish
the work in top machine learning venues.
