Available in PDF, EPUB and Kindle. Book excerpt: Time is involved in almost every scienti c eld one can think on. Observations of a phenomena are collected with the aim of study or explain its behavior. This collections lead to organized data called time series. Data mining community has spent a reasonable amount of time studying time series, in order to extract all meaningful knowledge from them. Humans are generally good comparing time series, but still, our capabilities are not scalable and we need to design algorithms and techniques that allow us to deal with high dimensional data and other problems. In this work we will focus in a speci c problem, extracting valid features of unlabeled time series obtained from aircraft sensors. These must serve as a summary of a ight and they also must include relevant details that serve to characterize it. This information will be used to feed an algorithm which can learn to classify ights in groups, reducing the number of necessary labeled data to obtain the desired accuracy using an active learning approach.

Download or read book Grammar Based Feature Generation for Time Series Prediction written by Anthony Mihirana De Silva and published by Springer. This book was released on 2015-02-14 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book proposes a novel approach for time-series prediction using machine learning techniques with automatic feature generation. Application of machine learning techniques to predict time-series continues to attract considerable attention due to the difficulty of the prediction problems compounded by the non-linear and non-stationary nature of the real world time-series. The performance of machine learning techniques, among other things, depends on suitable engineering of features. This book proposes a systematic way for generating suitable features using context-free grammar. A number of feature selection criteria are investigated and a hybrid feature generation and selection algorithm using grammatical evolution is proposed. The book contains graphical illustrations to explain the feature generation process. The proposed approaches are demonstrated by predicting the closing price of major stock market indices, peak electricity load and net hourly foreign exchange client trade volume. The proposed method can be applied to a wide range of machine learning architectures and applications to represent complex feature dependencies explicitly when machine learning cannot achieve this by itself. Industrial applications can use the proposed technique to improve their predictions.
Download or read book Discriminative Feature Extraction of Time series Data to Improve Temporal Pattern Detection Using Classification Algorithms written by David Stolze and published by . This book was released on 2018 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Time-series data streams often contain predictive value in the form of unique patterns. While these patterns may be used as leading indicators for event prediction, a lack of prior knowledge of pattern shape and irregularities can render traditional forecasting methods ineffective. The research in this thesis tested a means of predetermining the most effective combination of transformations to be applied to time-series data when training a classifier to predict whether an event will occur at a given time. The transformations tested on provided data streams included subsetting of the data, aggregation over various numbers of data points, testing of different predictive lead times, and converting the data set into a binary set of values. The benefit of the transformations is to reduce the data used for training down to only the most useful pattern containing points and clarify the predictive pattern contained in the set. In addition, the transformations tested significantly reduce the number of features used for classifier training through subsetting and aggregation. The performance benefit of the transformations was tested through creating a series of daily positive/negative event predictions over the span of a test set derived from each provided data stream. A landmarking system was then developed that utilizes the prior results obtained by the system to predetermine a “best fit” transformation to use on a new, untested data stream. Results indicate that the proposed set of transformations consistently result in improved classifier performance over the use of untransformed data values. Landmarking system testing shows that the use of prior knowledge results in selection of a near best fit transformation when using as few as 3 reference transformations."--Abstract.

Download or read book Feature Engineering for Machine Learning and Data Analytics written by Guozhu Dong and published by CRC Press. This book was released on 2018-03-14 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feature engineering plays a vital role in big data analytics. Machine learning and data mining algorithms cannot work without data. Little can be achieved if there are few features to represent the underlying data objects, and the quality of results of those algorithms largely depends on the quality of the available features. Feature Engineering for Machine Learning and Data Analytics provides a comprehensive introduction to feature engineering, including feature generation, feature extraction, feature transformation, feature selection, and feature analysis and evaluation. The book presents key concepts, methods, examples, and applications, as well as chapters on feature engineering for major data types such as texts, images, sequences, time series, graphs, streaming data, software engineering data, Twitter data, and social media data. It also contains generic feature generation approaches, as well as methods for generating tried-and-tested, hand-crafted, domain-specific features. The first chapter defines the concepts of features and feature engineering, offers an overview of the book, and provides pointers to topics not covered in this book. The next six chapters are devoted to feature engineering, including feature generation for specific data types. The subsequent four chapters cover generic approaches for feature engineering, namely feature selection, feature transformation based feature engineering, deep learning based feature engineering, and pattern based feature generation and engineering. The last three chapters discuss feature engineering for social bot detection, software management, and Twitter-based applications respectively. This book can be used as a reference for data analysts, big data scientists, data preprocessing workers, project managers, project developers, prediction modelers, professors, researchers, graduate students, and upper level undergraduate students. It can also be used as the primary text for courses on feature engineering, or as a supplement for courses on machine learning, data mining, and big data analytics.

Download or read book Machine Learning Techniques for Time Series Classification written by Michael Botsch and published by Cuvillier Verlag. This book was released on 2023-06-23 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classification of time series is an important task in various fields, e.g., medicine, finance, and industrial applications. This work discusses strong temporal classification using machine learning techniques. Here, two problems must be solved: the detection of those time instances when the class labels change and the correct assignment of the labels. For this purpose the scenario-based random forest algorithm and a segment and label approach are introduced. The latter is realized with either the augmented dynamic time warping similarity measure or with interpretable generalized radial basis function classifiers. The main application presented in this work is the detection and categorization of car crashes using machine learning. Depending on the crash severity different safety systems, e.g., belt tensioners or airbags must be deployed at time instances when the best-possible protection of passengers is assured.
