Download or read book Detecting and Quantifying Concept Drift for Data Stream written by Di Zhao and published by . This book was released on 2021 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concept drift describes changes in the underlying distribution of streaming data. Concept drift research involves the development of methodologies and techniques for drift detection, understanding, and adaptation. Data analysis shows that if the drift is not addressed, machine learning in a concept drift environment will result in poor learning results. Most drift detection methods focus on supervised learning, but the labels of streaming data are sometimes expensive. Most drift understanding methods quantify drift by data distribution. These methods require a certain number of data. This thesis investigates two research streams: (1) An unsupervised drift detection method, which does not require prior knowledge of the data distribution, and (2) A framework that quanti es the severity of concept drift from model perspective. In the rst part, we focus on feature drift that shifts boundaries of mode and present an unsupervised framework to detect feature drift without labels. The framework detects abrupt and gradual feature drift by two distance functions, Wasserstein distance and Energy distance, and discusses feature changes in the data stream. A less explored area is describing the changes in the data stream. Crucially, the ability to describe changes in the data stream would enable a better understanding of the changing dynamics in the relationships that take place over time. In particular, we seek to answer the following question: Whether the distribution changes of important features will also cause concept drift. Experimental results show that the proposed framework detects and describes the feature drift. In the second part, we propose a framework to quantify the severity of concept drift from model perspective. Our framework is based on the most popular data stream mining algorithm - Hoe ding Tree. Our approach quanti es the concept drift without data. This reduces the probability of data leaks. The severity of concept drift can be used as a guideline for choosing drift adaptation strategies. Our framework maps Hoe ding trees into groups of vectors and measures similarity and distance between vector groups. The larger similarity/lower distance indicates two trees are similar, and the lower similarity/larger distance indicates two trees are di erent.

Download or read book Machine Learning for Data Streams written by Albert Bifet and published by MIT Press. This book was released on 2018-03-16 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: A hands-on approach to tasks and techniques in data stream mining and real-time analytics, with examples in MOA, a popular freely available open-source software framework. Today many information sources—including sensor networks, financial markets, social networks, and healthcare monitoring—are so-called data streams, arriving sequentially and at high speed. Analysis must take place in real time, with partial data and without the capacity to store the entire data set. This book presents algorithms and techniques used in data stream mining and real-time analytics. Taking a hands-on approach, the book demonstrates the techniques using MOA (Massive Online Analysis), a popular, freely available open-source software framework, allowing readers to try out the techniques after reading the explanations. The book first offers a brief introduction to the topic, covering big data mining, basic methodologies for mining data streams, and a simple example of MOA. More detailed discussions follow, with chapters on sketching techniques, change, classification, ensemble methods, regression, clustering, and frequent pattern mining. Most of these chapters include exercises, an MOA-based lab session, or both. Finally, the book discusses the MOA software, covering the MOA graphical user interface, the command line, use of its API, and the development of new methods within MOA. The book will be an essential reference for readers who want to use data stream mining as a tool, researchers in innovation or data stream mining, and programmers who want to create new algorithms for MOA.

Download or read book Novelty Detection for Multivariate Data Streams with Probabilistic Models written by Christian Gruhl and published by BoD – Books on Demand. This book was released on 2022-01-01 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The autonomous detection of unexpected changes in data is called novelty detection. Multivariate data streams consisting of measurements from multiple sensors often form the basis to detect such changes. Specific examples of such changes are, for instance, cardiac arrhythmias, power failures, storms or network attacks. Accordingly, changes can affect both a system itself and the environment in which it is embedded. This doctoral thesis investigates methods for online novelty detection in multivariate data streams and presents the CANDIES methodology. A unique feature of this method is the explicit separation of the input space of a probabilistic model into different regions – High-Density Regions (HDR) and Low-Density Regions (LDR) – with detection techniques specifically designed for each. While other detectors can usually only detect novelties or anomalies in LDR, the CANDIES method can also identify novelties in HDR. It also offers possibilities to handle concept drift and noise in data streams. Another distinctive feature of CANDIES is the notion of novelties as an agglomeration of anomalies that have a certain relation to each other (spatially or temporally). Additionally, the focus of this work is also on the experimental evaluation of novelty detection algorithms in general. For this purpose, a data generator that can synthesise data streams and novelties is presented, and a new evaluation measure, the FDS, is specifically designed to evaluate novelty detection methods. All methods, algorithms and tools developed and used in this thesis are also publicly and freely available online.

Download or read book Dataset Shift in Machine Learning written by Joaquin Quinonero-Candela and published by MIT Press. This book was released on 2022-06-07 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of recent efforts in the machine learning community to deal with dataset and covariate shift, which occurs when test and training inputs and outputs have different distributions. Dataset shift is a common problem in predictive modeling that occurs when the joint distribution of inputs and outputs differs between training and test stages. Covariate shift, a particular case of dataset shift, occurs when only the input distribution changes. Dataset shift is present in most practical applications, for reasons ranging from the bias introduced by experimental design to the irreproducibility of the testing conditions at training time. (An example is -email spam filtering, which may fail to recognize spam that differs in form from the spam the automatic filter has been built on.) Despite this, and despite the attention given to the apparently similar problems of semi-supervised learning and active learning, dataset shift has received relatively little attention in the machine learning community until recently. This volume offers an overview of current efforts to deal with dataset and covariate shift. The chapters offer a mathematical and philosophical introduction to the problem, place dataset shift in relationship to transfer learning, transduction, local learning, active learning, and semi-supervised learning, provide theoretical views of dataset and covariate shift (including decision theoretic and Bayesian perspectives), and present algorithms for covariate shift.
