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.

Using LIME on text data

In the previous section, we discussed how LIME is an effective approach to explaining complicated black-box models trained on image datasets. Like images, text is also a form of unstructured data, which is very much different from structured tabular data. Explaining such black-box models trained on unstructured data is always very challenging. But LIME can also be applied to models trained on text data.

Using the LIME algorithm, we can analyze whether the presence of a particular word or group of words increases the probability of predicting a specific outcome. In other words, LIME helps to highlight the importance of text tokens or words that can influence the model's outcome toward a particular class. In this section, we will see how LIME can be used to interpret text classifiers.
