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 mission

In the United States, for the last two decades, private companies and non-profits have been developing criminal risk assessment tools, most of which employ statistical models. As many states can no longer afford their large prison populations, these methods have increased in popularity, guiding judges and parole boards through every step of the prison system. However, they often do more than guide a decision. They make them for justice system decision-makers because they assume it is correct. Worse of all, they don't exactly know how an assessment was made. The risk is usually calculated with a white-box model, but, in practice, a black-box model is used because it is proprietary. Predictive performance is also relatively low, with median AUC scores for nine tools ranging between 0.57 and 0.74. Still, validity and biases are rarely examined, especially by the criminal justice institutions that purchase them.

Even though traditional statistical methods are still...
