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.

Mission accomplished

The mission of this chapter was twofold, as outlined here:

  • Create a fair predictive model to predict which customers are most likely to default.
  • Create a robust causal model to estimate which policies are most beneficial to customers and the bank.

Regarding the first goal, we have produced four models with bias mitigation methods that are objectively fairer than the base model, according to four fairness metrics (SPD, DI, AOD, EOD)—when comparing privileged and underprivileged age groups. However, only two of these models are intersectionally fairer using both age group and gender, according to DFBA (see Figure 11.7). We can still improve fairness significantly by combining methods, yet any one of the four models improves the base model.

As for the second goal, the causal inference framework determined that any of the policies tested is better than no policy for both parties. Hooray! However, it yielded estimates that didn...
