Supervised Machine Learning in Python

在这门实践课程中，我们将专注于监督机器学习以及如何将其应用于 Python 编程语言。

监督机器学习是人工智能的一个分支，其目标是从数据集开始创建预测模型。通过对模型进行适当优化，可以创建数据的数学表示，以提取隐藏在我们数据库中的信息并将其用于推理和预测。

监督机器学习的一个非常强大的用途是计算特征重要性，它使我们更好地理解数据背后的信息，并允许我们仅考虑相关信息来降低问题的维数，丢弃所有无用的变量。计算特征重要性的常用方法是 SHAP 技术。

Description
In this practical course, we are going to focus on supervised machine learning and how to apply it in Python programming language.

Supervised machine learning is a branch of artificial intelligence whose goal is to create predictive models starting from a dataset. With the proper optimization of the models, it is possible to create mathematical representations of our data in order to extract the information that is hidden inside our database and use it for making inferences and 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 dimensionality of our problem considering only the relevant information, discarding all the useless variables. A common approach for calculating feature importance is the SHAP technique.

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