Deep Learning and XAI Techniques for Anomaly Detection

By: Cher Simon

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.

Considering intrinsic versus post hoc explainability

Can we ignore explainability and just trust state-of-the-art models? The short answer is no. A correct prediction does not adequately solve real-world problems. Users will not adopt an AI system unless it is trustworthy. Knowing why predictions are made is important to show how much an AI system can be trusted and provide insights into the best course of action when combined with domain expertise.

There are no hard-and-fast rules when choosing intrinsic versus post hoc explainability. For explainability’s sake, an intrinsic explainable model with adequate accuracy is always preferable over a complex model. Otherwise, post-processing explanation methods are alternatives to provide post hoc explainability after model training.

Inevitably, humans trust explanations selectively with unconscious bias based on profession, domain knowledge, and personal experience. Often, humans seek contrastive and interactive explanations...
