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 wrapper, hybrid, and advanced feature selection methods

The feature selection methods studied so far are computationally inexpensive because they require no model fitting or fitting simpler white-box models. In this section, we will learn about other, more exhaustive methods with many possible tuning options. The categories of methods included here are as follows:

  • Wrapper: Exhaustively searches for the best subset of features by fitting an ML model using a search strategy that measures improvement on a metric.
  • Hybrid: A method that combines embedded and filter methods with wrapper methods.
  • Advanced: A method that doesn’t fall into any of the previously discussed categories. Examples include dimensionality reduction, model-agnostic feature importance, and Genetic Algorithms (GAs).

And now, let’s get started with wrapper methods!

Wrapper methods

The concept behind wrapper methods is reasonably simple: evaluate different...
