## My Thesis

**Title:** *Random Matrix Theory for AI: From Theory to Practice. [slides] [manuscript]*

**Abstract:** *The AI era has driven the recent development of new algorithms and methods, often based on elementary principles allowing to handle large amounts of data of large dimensions. However, these large dimensional data impair the behavior of traditional methods that deserve to be revisited under the eye of more elaborate tools and methods. A better understanding of these methods in the bigdata regime indeed induces possibilities of improvements, thereby leading to the development of more efficient algorithms. The Random Matrix framework provides a powerful tool to understand and analyse the behavior of a wide range of ML methods under simple data models (such as the mixture of Gaussians model) in the large dimensional setting. My PhD thesis aims at going beyond the simple models hypothesis, by modelling data as Lipschitzally transformed Gaussian vectors which happen to be more appropriate for practical datasets (structured data, images, etc.).*
