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.

Understanding TCAV intuitively

The idea of TCAV was first introduced by Kim et al. in their work – Interpretability beyond Feature Attribution: Quantitative Testing with Concept Activation Vectors (TCAV) (https://arxiv.org/pdf/1711.11279.pdf). The framework was designed to provide interpretability beyond feature attribution, particularly for deep learning models that rely on low-level transformed features that are not human-interpretable. TCAV aims to explain the opaque internal state of the deep learning model using abstract, high-level, human-friendly concepts. In this section, I will present you with an intuitive understanding of TCAV and explain how it works to provide human-friendly explanations.

What is TCAV?

So far, we have covered many methods and frameworks to explain ML models through feature-based approaches. But it might occur to you that since most ML models operate on low-level features, the feature-based explanation approaches might highlight features that...
