## Stéphane Gaïffas – Teaching## Introduction to Machine Learning (Master M2MO)## SyllabusMachine learning is a scientific discipline that is concerned with the design and development of algorithms that allow computers to learn from data. A major focus of machine learning is to automatically learn complex patterns and to make intelligent decisions based on them. The set of possible data inputs that feed a learning task can be very large and diverse, which makes modeling and prior assumptions critical problems for the design of relevant algorithms. This course focuses on the methodology underlying supervised and unsupervised learning, with a particular emphasis on the mathematical formulation of algorithms, and the way they can be implemented and used in practice. The course will describe for instance some necessary tools from optimization theory, and explain how to use them for machine learning. Numerical illustrations and applications to datasets will be given for the methods studied in the course. ## FormatWe use `moodle`to centralize all teaching material (slides, notebooks, datasets, exercises)Courses on slides and blackboard, all material in English Practical sessions use `python`,`jupyter`,`scikit-learn`,`tensorflow`(deep learning) with the standard stack (`numpy`,`scipy`,`matplotlib`)Practical sessions will start with a quick introduction to `python`and the`jupyter notebook`, and the necessary libraries for data science
## SlackDuring the practical sessions, we will use slack for questions/answers Join using this link: https://join.slack.com/t/mlm2mo/shared_invite/MjM3NDcyNjY4Mjc0LTE1MDQ3NzQ2NzMtNWQ3N2I2NmVhMg
