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 provide an objective evaluation of the fruit classification model for the convenience store chain. The predictive performance on out-of-sample validation images was dismal! You could have stopped there, but then you would not have known how to make a better model.

However, the predictive performance evaluation was instrumental in deriving specific misclassifications, as well as correct classifications, to assess using other interpretation methods. To this end, you ran a comprehensive suite of interpretation methods, including activation, gradient, perturbation, and backpropagation-based methods. The consensus between all the methods was that the model was having the following issues:

  • Differentiating between the background and the fruit
  • Understanding that different fruit classes share some color hues
  • Confounding lighting conditions such as specular highlights and shadows as specific fruit characteristics
  • Being confused...
