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.

Reviewing filter-based feature selection methods

Filter-based methods independently select features from a dataset without employing any ML. These methods depend only on the variables’ characteristics and are relatively effective, computationally inexpensive, and quick to perform. Therefore, being the low-hanging fruit of feature selection methods, they are usually the first step in any feature selection pipeline.

Filter-based methods can be categorized as:

  • Univariate: Individually and independently of the feature space, they evaluate and rate a single feature at a time. One problem that can occur with univariate methods is that they may filter out too much since they don’t take into consideration the relationship between features.
  • Multivariate: These take into account the entire feature space and how features interact with each other.

Overall, for the removal of obsolete, redundant, constant, duplicated, and uncorrelated features, filter...
