Overview of this book

Despite promising advances, the opaque nature of deep learning models makes it difficult to interpret them, which is a drawback in terms of their practical deployment and regulatory compliance. Deep Learning and XAI Techniques for Anomaly Detection shows you state-of-the-art methods that’ll help you to understand and address these challenges. By leveraging the Explainable AI (XAI) and deep learning techniques described in this book, you’ll discover how to successfully extract business-critical insights while ensuring fair and ethical analysis. This practical guide will provide you with tools and best practices to achieve transparency and interpretability with deep learning models, ultimately establishing trust in your anomaly detection applications. Throughout the chapters, you’ll get equipped with XAI and anomaly detection knowledge that’ll enable you to embark on a series of real-world projects. Whether you are building computer vision, natural language processing, or time series models, you’ll learn how to quantify and assess their explainability. By the end of this deep learning book, you’ll be able to build a variety of deep learning XAI models and perform validation to assess their explainability.

Problem

NLP explainability typically involves removing or masking random words from a dataset. Extending the same Amazon Customer Reviews dataset, we will review an NLP anomaly detection example using Cleanlab, https://github.com/cleanlab/cleanlab, an open source library, to find potential label errors for text data. Then, we will use SHAP, https://github.com/slundberg/shap, to evaluate post hoc local explainability for model predictions by visualizing feature attributions of individual classes based on computed SHAP values.

Post hoc local explainability means assessing how a particular decision or prediction is made after model training. Using a fine-tuned bidirectional encoder representations from transformers (BERT) model, we will classify positive versus negative sentiments for the Amazon Customer Reviews dataset and compare predicted label errors.

The following section provides an end-to-end solution walk-through.
