Definition

Anomaly Detection is the process of uncovering anomalies, errors, bugs, and defects in software to eradicate them and increase the overall quality of a system. Finding anomalies in big data analytics is especially important. Big data is “unstructured” by definition, hence, the process of structuring it is continually presented with anomaly detection activities.

Introduction

Data engineering is a challenging process. Different stages of the process affect the outcome in a variety of ways. Manpower, system design, data formatting, variety of data sources, size of the software, and project budget are among the variables that could alter the outcome of an engineering project. Nevertheless, software and data anomalies pose one of the most challenging obstacles in the success of any project. Anomalies have postponed space shuttle launches, caused problems for airplanes, and disrupted credit card and...
