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.

Shielding against any evasion attack via adversarial training of a robust classifier

In Chapter 8, Visualizing Convolutional Neural Networks, we faced a fruit image classifier that would likely perform poorly in the intended environment of a convenience store self-serve checkout. The abysmal performance on out-of-sample data was due to the classifier being trained on many images of one or two fruits per class, taken from entirely different angles with consistent illumination. It turns out that the variety of angles wasn't as important as the variety of fruit and illumination! The chapter's conclusion called for the training of a network with images representing their intended environment, to make for a more robust model.

For model robustness, training data variety is critical, but only if it represents the intended environment. In statistical terms, it's a question of using samples for training that accurately depict the population so that the model learns to classify...
