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.

Exploring the practical applications of TCAV

In this section, we will explore the practical applications of TCAV for explaining pre-trained image explainers with concept importance. The entire notebook tutorial is available in the code repository of this chapter at https://github.com/PacktPublishing/Applied-Machine-Learning-Explainability-Techniques/blob/main/Chapter08/Intro_to_TCAV.ipynb. This tutorial is presented based on the notebook provided in the original GitHub project repository of TCAV https://github.com/tensorflow/tcav. I recommend that you all refer to the main project repository of TCAV since the credit for implementation should go to the developers and contributors of TCAV.

In this tutorial, we will cover how to apply TCAV to validate the concept importance of the concept of stripes as compared to the honeycomb pattern for identifying tigers. The following images illustrate the flow of the approach used by TCAV to ascertain concept importance using a simple visualization...
