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.

Example-based methods

Another approach to model explainability is provided by example-based methods. The idea of example-based methods is similar to how humans try to explain a new concept. As human beings, when we try to explain or introduce something new to someone else, often, we try to make use of examples that our audience can relate to. Similarly, example-based methods, in the context of XAI, try to select certain instances of the dataset to explain the behavior of the model. It assumes that observing similarities between the current instance of the data with a historic observation can be used to explain black-box models.

These are mostly model-agnostic approaches that can be applied to both structured and unstructured data. If the structured data is high-dimensional, it becomes slightly challenging for these approaches, and all the features cannot be included to explain the model. So, it works well only if there is an option to summarize the data instance or pick up only...
