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.

The mission

In the United States, for the last two decades, private companies and nonprofits have developed criminal Risk Assessment Instruments/Tools (RAIs), most of which employ statistical models. As many states can no longer afford their large prison populations, these methods have increased in popularity, guiding judges and parole boards through every step of the prison system.

These are high-impact decisions that can determine if a person is released from prison. Can we afford for these decisions to be wrong? Can we accept the recommendations from these systems without understanding why they were made? Worst of all, we don’t exactly know how an assessment was made. The risk is usually calculated with a white-box model, but, in practice, a black-box model is used because it is proprietary. Predictive performance is also relatively low, with median AUC scores for a sample of nine tools ranging between 0.57 and 0.74 according to the paper Performance of Recidivism Risk...
