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.

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, snow_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 for 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...
