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.

Comparing SHAP with LIME

As you will have noticed by now, both SHAP and LIME have limitations, but they also have strengths. SHAP is grounded in game theory and approximate Shapley values, so its SHAP values mean something. These have great properties such as additivity, efficiency, and substitutability that make it consistent but violate the dummy property. It always adds up and doesn't need parameter tuning to accomplish this. However, it's more suited for global interpretations, and one of its most model-agnostic explainers, KernelExplainer, is painfully slow. KernelExplainer also deals with missing values by using random ones, which can put too much weight on unlikely observations.

LIME is speedy, very model-agnostic, and adaptable to all kinds of data. However, it's not grounded on strict and consistent principles but has the intuition that neighbors are alike. Because of this, it can require tricky parameter tuning to define the neighborhood size optimally,...
