When I build a machine learning model for classification problems, one of the questions that I ask myself is why is my model not crap? Sometimes I feel that developing a model is like holding a grenade, and calibration is one of my safety pins. In this post, I will walk through the concept of calibration, then show in Python how to make diagnostic calibration plots.
