Federated learning trains one shared machine-learning model across many devices, such as phones or sensors, without collecting their raw data in one place. This protects privacy and suits devices that must respond quickly.

What they work on

  1. Build theory for federated learning that uses the statistical structure of each device's data, to explain why it succeeds in practice where optimization-only analyses predict failure.
  2. Replace overly pessimistic bounded gradient dissimilarity assumptions with more realistic conditions, using tools from statistical learning and high-dimensional probability.
  3. Design new federated learning algorithms that stay accurate despite large differences in data across devices, faulty clients and outside attacks, drawing on distributed computing and optimization.

More about the research

But the devices hold very different data, some fail or misbehave, and some may be attacked. Current theory often predicts poor results that do not match how well federated learning works in practice. This project aims to close that gap with stronger mathematical foundations and more robust algorithms.

Why it matters

Federated learning lets fields such as healthcare, self-driving vehicles, language processing and manufacturing train models without sharing private raw data. Theory that matches real performance, and algorithms that tolerate uneven data, faulty devices and attacks, could make these systems more reliable and trustworthy on edge devices.
