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 first part of the mission was to understand risk factors for cardiovascular disease, and you've determined that the top four risk factors are systolic blood pressure (ap_hi), age, cholesterol, and weight according to the logistic regression model, of which only age is non-modifiable. However, you also realized that systolic blood pressure (ap_hi) is not as meaningful on its own since it relies on diastolic blood pressure (ap_lo) for interpretation. The same goes for weight and height. We learned that the interaction of features plays a crucial role in interpretation, and so does their relationship with each other and the target variable, whether linear or monotonic. Furthermore, the data is only a representation of the truth, which can be wrong. After all, we found anomalies that, left unchecked, can bias our model.

Another source of bias is how the data was collected. After all, you can wonder why the model's top features were all objective and...
