Stability in Machine Learning through its algorithms

Objectives

  1. Clarify the fundamental concepts of Machine Learning in various algorithms such as overfitting, regularization and computational cost.

  2. Know the details of three famous and useful algorithms (models) in Machine Learning: Neural Networks, Support Vector Machines and Decision Trees.

  3. Invite students to the Boosting method with a focus on their applications to Machine Learning as well as its limitations.

  4. Study the details behind some stochastic algorithms in Machine Learning.

  5. Once the above objectives have been met, we seek to initiate students in the ideas of stability within Machine Learning, we will do so through concrete examples with the algorithms and meta-algorithms detailed in the agenda.
