Learn Python by Building Data Science Applications

Training a Machine Learning Model

As we have learned in the last chapter, data always contains valuable insights. Exploring with statistics, filters, and charts is a great tool for this. However, data has another internal value—its predictive power; it can be used to fit an algorithm (machine learning model) that will then be able to predict the values of interest and explain its judgment.

Machine learning (ML) is a large and complex topic that is clearly out of the scope of this book. Indeed, building an advanced and complex model requires deep theoretical knowledge of the specific domain and a lot of time and exploration. However, some ML models are very simple and easy to comprehend, and the basic underlying principles are all the same. ...
