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

You have decided to do the following:

  • Train proxy models: You don't have the original features or model, but all is not lost because you have the COMPAS scores – the labels. And we also have relevant features to the problem we can connect to these labels with models. By approximating the COMPAS model via the proxies, you can assess its unfairness of the labels. In this chapter, we will train a CatBoost model and a neural network model.
  • Anchor explanations: Using this method will unearth insights into why the proxy model makes specific predictions using a series of rules called anchors, which tell you where the decision boundaries lie. The boundaries are relevant for our mission because we want to know why the defendant has been wrongfully predicted to recidivate. It's an approximate boundary to the original model, but there's still some truth to it.
  • Counterfactual explanations: The opposite concept to anchors is about understanding...
