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.

Mission accomplished

The mission was to understand how fuel efficiency was impacted over the years by the potential predictors in the dataset. We determined that the most significant fuel efficiency predictors, by far, are pollution-related, and that tailpipe CO2 in grams/mile (co2TailpipeGpm) is the one that stands out. Both pollution and fuel inefficiency decrease with every year. Likewise, they increase with the number of cylinders and when it's a diesel engine (fuelType_Diesel). None of this should be surprising to anybody who knows about cars' evolution over the past few decades.

However, there were some revealing insights. For instance, SHAP dependence plots (Figures 5.12 and 5.14) helped us understand why the co2 and ghgScore features are redundant. And as depicted by an interaction ALE plot (Figure 5.19) there might be some data quality issues with co2TailpipeGpm before 2004, which should be investigated further. Global surrogates distilled a sense of hierarchy...
