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 was to provide an objective evaluation of the garbage classification model for the municipal recycling plant. The predictive performance on out-of-sample validation images was dismal! You could have stopped there, but then you would not have known how to make a better model.

However, the predictive performance evaluation was instrumental in deriving specific misclassifications, as well as correct classifications, to assess using other interpretation methods. To this end, you ran a comprehensive suite of interpretation methods, including activation, gradient, perturbation, and backpropagation-based methods. The consensus between all the methods was that the model was having the following issues:

  • Differentiating between the background and the objects
  • Understanding that different objects share similar color hues
  • Confounding lighting conditions, such as specular highlights as specific material characteristics, like with the wine...
