Overview of this book

Interpretable Machine Learning with Python, Second Edition, brings to light the key concepts of interpreting machine learning models by analyzing real-world data, providing you with a wide range of skills and tools to decipher the results of even the most complex models. Build your interpretability toolkit with several use cases, from flight delay prediction to waste classification to COMPAS risk assessment scores. This book is full of useful techniques, introducing them to the right use case. Learn traditional methods, such as feature importance and partial dependence plots to integrated gradients for NLP interpretations and gradient-based attribution methods, such as saliency maps. In addition to the step-by-step code, you’ll get hands-on with tuning models and training data for interpretability by reducing complexity, mitigating bias, placing guardrails, and enhancing reliability. By the end of the book, you’ll be confident in tackling interpretability challenges with black-box models using tabular, language, image, and time series data.

Discovering newer interpretable (glass-box) models

In the last decade, there have been significant efforts in both industry and in academia to create new models that can have enough complexity to find the sweet spot between underfitting and overfitting, known as the bias-variance trade-off, but retain an adequate level of explainability.

Many models fit this description, but most of them are meant for specific use cases, haven’t been properly tested yet, or have released a library or open-sourced code. However, two general-purpose ones are already gaining traction, which we will look at now.

Explainable Boosting Machine (EBM)

EBM is part of Microsoft’s InterpretML framework, which includes many of the model-agnostic methods we will use later in the book.

EBM leverages the GAMs we mentioned earlier, which are like linear models but look like this:

Individual functions f1 through fp are fitted to each feature using spline functions. Then a link...
