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.

Identifying influential features with factor prioritization

The Morris Method is one of several global sensitivity analysis methods that range from simpler Fractional Factorial to complicated Monte Carlo Filtering. Morris is somewhere in-between this spectrum, falling into two categories. It uses one-at-a-time sampling, which means that only one value changes between consecutive simulations. It's also elementary effects (EE), which means that it doesn't quantify the exact effect of a factor in a model but rather gauges its importance and relationship with other factors. By the way, factor is just another word for a feature or variable that's commonly used in applied statistics. To be consistent with the related theory, we will use this word in this and the next section.

Another property of Morris is that it's less computationally expensive than the variance-based methods we will study next. It can provide more insights than simpler and less costly methods such as regression...
