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.

Evaluating and certifying adversarial robustness

It's necessary to test your systems in any engineering endeavor to see how vulnerable they are to attacks or accidental failures. However, security is a domain where you must stress-test your system to ascertain what level of attack is needed to make your system break down beyond an acceptable threshold. Furthermore, figuring out what level of defense is needed to curtail an attack is useful information too.

Comparing model robustness with attack strength

We now have two classifiers we can compare against an equally strengthed attack, and we can try different attack strengths to see how they fare across all of them. We will use FGSM because it's fast, but you could use any method!

The first attack strength we can assess is no attack strength. In other words, what is the classification accuracy against the test dataset with no attack? We had already stored the predicted labels for both the base (y_test_pred) and robust...
