Biography
Chloé Agathe Azencott is a researcher specializing in bioinformatics and machine learning applied to genomics and precision medicine. Her work focuses on developing computational methods for analyzing complex biomedical data, particularly in the context of genome-wide association studies (GWAS) or large genomic data or the prediction of drug-target interactions. Her expertise includes the integration of prior biological knowledge, such as gene interaction networks, to enhance the robustness and interpretability of predictive models. Throughout her research, she has contributed to methodological advances in the detection of epistasis, feature selection, and multi-task machine learning, while addressing challenges related to data sparsity and high dimensionality.

Data Science
Statistical concepts (population, estimation); dimensionality reduction; best practices (visualization, representativeness, confidentiality, algorithmic bias); supervised learning (empirical risk minimization, regularization, feature selection, and validation).
Introduction to machine learning
In the age of data, various domains (Internet, marketing, logistics, biology, etc.) are accummulating enormous amounts of data, giving rise to the need for growing needs for automated tools that are able to exploit data of various nature. In particular, machine learning algorithms such as artificial neural networks, support vector machines or random forests can provide more powerful modeling and analyzes than classical linear statistical methods. This course aims at providing an overview of these algorithms, as well as their theoretical and methodological framework, through a diversity of applications.
