Introduction to machine learning

This course is intended for beginners who have no or limited experience with machine learning and want to do their first steps in this field. The participants will learn what machine learning is, what types of ML are the most typical in practical applications and how the basic algorithms work. We are not going to sink into mathematical formulas or complex proofs. Instead, we will focus on intuitive understanding of the principles, which are necessary for the ability to design machine learning models. The course covers introduction to classification, regression, clustering, and practical basics of artificial neural networks in Python.
