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

The task at hand is to find which features—whether quiz answers, technical, and demographic details—signal birth order the most, and if they are reliable to use for this purpose. One way to do this is by creating classification models to predict birth order, and then doing the following:

  • Using the model's intrinsic parameters to discover which features impact the model the most. This concept is called feature importance, and it's a global modular interpretation method. This was explained in Chapter 2, Key Concepts of Interpretability, but we will go into more detail in this chapter.
  • Exploring feature importance further with a more reliable permutation-based method called PFI.
  • Examining the marginal impact to the outcome of the most important features with PDPs. That way, we can tell which feature values correlate the most with the predictions.
  • Getting a more granular visualization of how individual features impact the models...
