In this practicalcourse, we are going to focus on supervised machine learningand how to apply it in Python programming language.

Supervised machine learning is a branch of artificial intelligence whose goal is to create predictive modelsstarting from a dataset. With the proper optimization of the models, it is possible to create mathematical representationsof our data in order to extract the informationthat is hidden inside our database and use it for making inferencesand predictions.

A very powerful use of supervised machine learning is the calculation of feature importance, which makes us better understand the information behind data and allows us to reduce the dimensionalityof our problem considering only the relevant information, discarding all the useless variables. A common approach for calculating feature importance is the SHAPtechnique.

Finally, the proper optimization of a model is possible using some hyperparameter tuningtechniques that make use of cross-validation.
