Interpretable Machine Learning with Python

By: Serg Masís

Overview of this book

Do you want to gain a deeper understanding of your models and better mitigate poor prediction risks associated with machine learning interpretation? If so, then Interpretable Machine Learning with Python deserves a place on your bookshelf. We’ll be starting off with the fundamentals of interpretability, its relevance in business, and exploring its key aspects and challenges. As you progress through the chapters, you'll then focus on how white-box models work, compare them to black-box and glass-box models, and examine their trade-off. You’ll also get you up to speed with a vast array of interpretation methods, also known as Explainable AI (XAI) methods, and how to apply them to different use cases, be it for classification or regression, for tabular, time-series, image or text. In addition to the step-by-step code, this book will also help you interpret model outcomes using examples. You’ll get hands-on with tuning models and training data for interpretability by reducing complexity, mitigating bias, placing guardrails, and enhancing reliability. The methods you’ll explore here range from state-of-the-art feature selection and dataset debiasing methods to monotonic constraints and adversarial retraining. By the end of this book, you'll be able to understand ML models better and enhance them through interpretability tuning.

The approach

Upon careful consideration, you have decided to approach this both as a regression problem and a classification problem. Therefore, you will produce models that predict minutes delayed as well as models that classify whether flights were delayed by more than 15 minutes or not. For interpretation, using both will enable you to use a wider variety of methods, and expand your interpretation accordingly. Also, dimensionality reduction can only further enrich interpretation possibilities. So we will approach this example by taking the following steps:

  1. Predicting minutes delayed with various regression methods
  2. Classifying flights as delayed or not delayed with various classification methods
  3. Visualizing delayed flights with dimensionality reduction methods

These steps in the Reviewing traditional model interpretation methods section are followed by conclusions spread out in the rest of the sections of this chapter.
