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.

Global surrogates

Surrogate model is an overloaded term. It is used in engineering, statistics, economics, and physics, to name a few, often in the context of metamodels, mathematical optimizations, or simulations.

In the context of machine learning interpretation methods, global surrogate model usually refers to a white-box model that you train with the black-box models' predictions. We do this to extract insights from the white-box model's intrinsic parameters, much like we did in Chapter 3, Interpretation Challenges. There is also another way to use surrogate models: to use a black-box model to approximate and evaluate another model that you don't have access to, but you have its predictions. We will do just this in Chapter 7, Anchor and Counterfactual Explanations, but we prefer the term proxy model for this kind of surrogate.

You don't need any fancy libraries to create a global surrogate. You can use any of the white-box models we discussed in Chapter...
