When information in the data warehouse is processed, it follows a definite pattern. An unexpected deviation in the data pattern from the usual behavior is called an anomaly. The anomaly in the data is also referred to as noise, outlier, spammer, deviations, novelties and exceptions. Identification of the rare items, events, observations, patterns which raise suspension by differing significantly from the majority of data is called anomaly detection. With progress in the technologies and the widespread use of data for the purpose for business the increase in the spams faced by the individuals and the companies are increasing day by day. This noisy data has boomed as a major problem in various areas such as Internet of Things, web service, Machine Learning, Artificial Intelligence, Deep learning, Image Processing, Cloud Computing, Audio processing, Video Processing, VoIP, Data Science, Wireless Sensor etc. Identifying the anomaly data and filtering them before processing is a major challenge for the data analyst. This anomaly is unavoidable in all areas of research. This book covers the techniques and algorithms for detecting the deviated data. This book will mainly target researchers and higher graduate learners in computer science and data science.

This book provides a comprehensive overview of the research on anomaly detection with respect to context and situational awareness that aim to get a better understanding of how context information influences anomaly detection. In each chapter, it identifies advanced anomaly detection and key assumptions, which are used by the model to differentiate between normal and anomalous behavior. When applying a given model to a particular application, the assumptions can be used as guidelines to assess the effectiveness of the model in that domain. Each chapter provides an advanced deep content understanding and anomaly detection algorithm, and then shows how the proposed approach is deviating of the basic techniques. Further, for each chapter, it describes the advantages and disadvantages of the algorithm. The final chapters provide a discussion on the computational complexity of the models and graph computational frameworks such as Google Tensorflow and H2O because it is an important issue in real application domains. This book provides a better understanding of the different directions in which research has been done on deep semantic analysis and situational assessment using deep learning for anomalous detection, and how methods developed in one area can be applied in applications in other domains. This book seeks to provide both cyber analytics practitioners and researchers an up-to-date and advanced knowledge in cloud based frameworks for deep semantic analysis and advanced anomaly detection using cognitive and artificial intelligence (AI) models.

With the rapid development of smart grids, the detection of anomalies is essential to improve the quality and security protection of the grid. The identification of anomalies not only saves valuable time but also reduces maintenance costs. Due to the increasing deployment of distributed energy resources, traditional methods of protecting the grid that rely on simple linear models and manual inspections are no longer sufficient. Meanwhile, the massive amount of data generated by smart meters and phasor measurement units provide opportunities to better monitor and control power grids in real-time. Due to this advantage of data availability, various machine learning and deep learning methods have been proposed and are currently demonstrating successful results in anomaly detection in power systems. While previously proposed artificial intelligence techniques can successfully de- tect anomalies, most of them tend to require large amounts of simulated data of all different types of anomalies for training their framework. However, anomalous data may be rare in power distribution systems. In addition, their static training model makes them vulnerable to new data from different distributions entering the system. To address these drawbacks, we propose data-driven frameworks based on deep learning network models to directly detect anomalies in power distribution systems. Anomalies are generally defined as observations that deviate from the standard, normal or expected values. Specifically, this work is divided into two phases. In the first phase, we consider anomalies as events caused by changes in the distribution system load, such as customer disconnection from the grid. A long short-term memory network is proposed to predict the next time step of the voltage magnitude of all buses in the distribution system. A threshold function based on Euclidean distance is then used to detect voltage anomalies by utilizing only normal data. The results corresponding to this proposed framework have been successfully tested using a real distribution network. In the second phase, we aim to classify faults and locate faulted lines in partially observable distribution systems using convolutional neural networks. To improve the robustness of the classification and localization performance, we extract feature vectors with measurements in the observable buses as inputs to the proposed classifier. In addition, we incorporate an online continuous learning algorithm to accommodate variations in the level of integration of distributed energy resources and changes in the load of the distribution system over time. Unlike previous data-driven approaches, the proposed method also deals with imbalanced learning tasks, as fault data are often rare. The performance of the method has been tested and validated by simulating ten faults on a real distribution feeder model.

Detection of anomalies in data is one of the fundamental machine learning tasks. Anomaly detection provides the core technology for a broad spectrum of security-centric applications. In this dissertation, we examine various aspects of anomaly based intrusion detection in computer security. First, we present a new approach to learn program behavior for intrusion detection. Text categorization techniques are adopted to convert each process to a vector and calculate the similarity between two program activities. Then the k-nearest neighbor classifier is employed to classify program behavior as normal or intrusive. We demonstrate that our approach is able to effectively detect intrusive program behavior while a low false positive rate is achieved. Second, we describe an adaptive anomaly detection framework that is de- signed to handle concept drift and online learning for dynamic, changing environments. Through the use of unsupervised evolving connectionist systems, normal behavior changes are efficiently accommodated while anomalous activities can still be recognized. We demonstrate the performance of our adaptive anomaly detection systems and show that the false positive rate can be significantly reduced.
