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 approach

You have decided to use local model interpretation to explain why each bar is rated as it is. To that end, you will prepare the dataset and then train classification models to predict if chocolate-bar ratings are above or equal to Highly Recommended, because the client would like all their bars to fall above this threshold. You will need to train two models: one for tabular data, and another NLP one for the words used to describe the chocolate bars. We will employ support vector machines (SVMs) and Light Gradient Boosting Machine (LightGBM), respectively, for these tasks. If you haven't used these black-box models, no worries—we will briefly explain them. Once you train the models, then comes the fun part: leverage two local model-agnostic interpretation methods to understand what makes a specific chocolate bar less than Highly Recommended or not. These methods are SHAP and LIME, which when combined will provide a richer explanation to convey...
