Topics of interest

Unsupervised learning, distributed machine learning, modeling and algorithmic design for distributed systems and networks

Project in Prairie

Laurent Massoulié will develop distributed algorithms for learning from data spread over several machines, to efficiently exploit communication resources between data locations, and storage and compute resources at data locations. He will develop efficient algorithms for unsupervised learning from ‘graphical data’. He will also address fairness and privacy challenges of machine learning, in particular in the contexts of recommender systems and matching markets.


Relational, or ‘graphical’ data is becoming ubiquitous (e.g. social / biological / transportation networks, energy grids…). Its treatment calls for new methods to construct and process adequate representations of data points in suitable spaces. There are many important scenarios where data must be distributed on several network locations, e.g. when it is too large to fit on a single machine, or when it can’t leave administrative boundaries due to privacy concerns. New distributed algorithms, and possibly new network architectures are needed for efficient learning from data distributed over a network.
