Learn how to
harness large amounts of data
Developing mathematics and algorithmics to analyze and process large amounts of data is a crucial challenge, with the need to account for phenomena that commonly occur with high-dimensional data by utilizing emerging methods and concepts in probabilities and statistics.
Studies conducted at Dauphine-PSL on these topics are both methodological and digital.
Inverse problems
High-dimensional statistics
High-dimensional probability
Random graphs and matrices
Markov chain Monte Carlo
Stochastic algorithms
Approximate Bayesian computation
Applications
The scope of application is massive, potentially covering the full spectrum of data science: social networks, astrophysics, genetics, neuroscience, and more.
The choice and validation of models are also of interest to researchers at Dauphine-PSL.
In this area, creating toolboxes for practitioners and introducing algorithms based on massively parallel architecture has proven useful.
Our Research in the University's Labs
This topic of high-dimensional phenomena is explored at Dauphine-PSL, especially at CEREMADE, in relation to high-dimensional statistics, stochastic inverse problems, random graph and random matrix models, approximate Bayesian statistics (ABC methods), and stochastic algorithms.
These research initiatives draw upon connections with mathematical analysis and statistical physics.
