Applied Machine Learning Explainability Techniques

By: Aditya Bhattacharya

Overview of this book

Explainable AI (XAI) is an emerging field that brings artificial intelligence (AI) closer to non-technical end users. XAI makes machine learning (ML) models transparent and trustworthy along with promoting AI adoption for industrial and research use cases. Applied Machine Learning Explainability Techniques comes with a unique blend of industrial and academic research perspectives to help you acquire practical XAI skills. You'll begin by gaining a conceptual understanding of XAI and why it's so important in AI. Next, you'll get the practical experience needed to utilize XAI in AI/ML problem-solving processes using state-of-the-art methods and frameworks. Finally, you'll get the essential guidelines needed to take your XAI journey to the next level and bridge the existing gaps between AI and end users. By the end of this ML book, you'll be equipped with best practices in the AI/ML life cycle and will be able to implement XAI methods and approaches using Python to solve industrial problems, successfully addressing key pain points encountered.

Types of model explainability methods

There are different approaches that you can use to provide model explainability. Certain techniques are specific to a model, and certain approaches are applied to the input and output of the model. In this section, we will discuss the different types of methods used to explain ML models:

  • Knowledge extraction methods: Extracting key insights and statistical information from the data during Exploratory Data Analysis (EDA) and post-hoc analysis is one way of providing model-agnostic explainability. Often, statistical profiling methods are applied to extract the mean and median values, standard deviation, or variance across the different data points, and certain descriptive statistics are used to estimate the expected range of outcomes.

Similarly, other insights using correlation heatmaps, decomposition trees, and distribution plots are also used to observe any relationships between the features to explain the model's results. For...
