At Last! Time Series Joins, Motifs, Discords and Shapelets at Interactive Speeds
Eamonn Keogh
Video in druga učna gradiva
Oznake: computer science;data science
Given the ubiquity of time series, the last decade has seen a flurry of activity in time series data mining. Some of the most useful and frequently used primitives “reason” about the shapes of subsequences found in longer time series. Examples include Time Series Joins, Motifs, Discords and Shapelet ...

Extracting Optimal Performance From Dynamic Time Warping
Eamonn Keogh , Abdullah Al Mueen
Video in druga učna gradiva
Oznake: computer science;data science
Dynamic Time Warping (DTW) is a distance measure that compares two time series after optimally aligning them. DTW is being used for decades in thousands of academic and industrial projects despite the very expensive computational complexity, O(n2). These applications include data mining, image proce ...

Time Series data Mining Using the Matrix Profile: A Unifying View of Motif Discovery, Anomaly Detection, Segmentation, Classification, Clustering and Similarity Joins
Abdullah Al Mueen , Eamonn Keogh
Video in druga učna gradiva
Oznake: computer science;data science
The Matrix Profile (and the algorithms to compute it: STAMP, STAMPI, STOMP, SCRIMP and GPU-STOMP), has the potential to revolutionize time series data mining because of its generality, versatility, simplicity and scalability. In particular it has implications for time series motif discovery, time s ...
