Abstract

Anomaly detection refers to the problem of finding rare patterns in data which raise suspicions because they do not comply with an expected behavior. We can consider different kinds of applications like intrusion detection, image processing, system health monitoring and sensor networks. For example, an anomalous pattern coming from sensors on a machine could mean that the machine is ready to break. 
Most of the current studies on anomaly detection do not consider recent/past events to detect possible new incoming outliers. The use of Long Short-Term Memory (LSTM) networks is then proposed to deal with time dependent data related with anomaly detection problems.
The goal of Support Vector Data Description (SVDD) is to describe a realistic domain for the data, excluding superfluous space. The resulting boundary can then be used to detect outliers.

In this master thesis, we consider a LSTM-based prediction model for sensor readings coming from a pulp and paper manufacturing machine. Anomalies will then result from too large prediction errors. We compare the SVDD and a discrimination rule based on the assumption of normality for the errors. In the final chapter, we show that for a real world applications the Gaussian distribution for the errors cannot hold and that the need of a non-parametric data descriptions using kernels is real.

Abstract

This reprint introduces advanced prediction models focused on power load forecasting. Models based on artificial intelligence and more traditional approaches are shown, demonstrating the real possibilities of use to improve prediction in this field. Models of LSTM neural networks, LSTM networks with a SESDA architecture, in even LSTM-CNN are used. On the other hand, multiple seasonal Holt-Winters models with discrete seasonality and the application of the Prophet method to demand forecasting are presented. These models are applied in different circumstances and show highly positive results. This reprint is intended for both researchers related to energy management and those related to forecasting, especially power load.

Abstract

This book presents recent research results related to various applications of computer vision methods in the widely understood contexts of automation and robotics. As the current progress of image analysis applications may be easily observed in various areas of everyday life, it becomes one of the most essential elements of development of Industry 4.0 solutions. Some of the examples, partially discussed in individual chapters, may be related to the visual navigation of mobile robots and drones, monitoring of industrial production lines, non-destructive evaluation and testing, monitoring of the IoT devices or the 3D printing process and the quality assessment of manufactured objects, video surveillance systems, and decision support in autonomous vehicles.
