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.

Quantifying uncertainty and cost sensitivity with factor fixing

With the Morris indices, it became evident that all the factors are non-linear or non-monotonic. There's a high degree of interactivity between them – as expected! It should be no surprise that climate factors (temp, rain_1h, and cloud_coverage) are likely multicollinear with hr. There are also patterns to be found between hr, is_holiday, and dow and the target. Many of these factors most definitely don't have a monotonic relationship with the target. We know this already. For instance, traffic doesn't consistently increase as hours increase throughout the day. That's not the case between days of the week either!

However, we didn't know to what degree is_holiday and temp impacted the model, particularly during the crew's working hours, which was an important insight. That being said, factor prioritization with Morris indices is usually to be taken as a starting point or "first...
