Decision trees and churn rate

The course is an invitation to use decision trees for binary classification problems,

The course is divided into classes as follows:
1. What is machine learning and what are decision trees?

2. A look at Python.

3. Formal description of algorithms that learn decision trees
4. Implementation of decision trees for churn rate prediction. 5. Advanced aspects of decision trees (three hours).
