ai.libs.jaicore.ml.classification.singlelabel.timeseries.shapelets.search.ExhaustiveMinimumDistanceSearchStrategy

public class ExhaustiveMinimumDistanceSearchStrategy
extends AMinimumDistanceSearchStrategy

Class implementing a search strategy used for finding the minimum distance of a Shapelet object to a time series. The approach uses an exhaustive search as described in the paper 'Jason Lines, Luke M. Davis, Jon Hills, and Anthony Bagnall. 2012. A shapelet transform for time series classification. In Proceedings of the 18th ACM SIGKDD international conference on Knowledge discovery and data mining (KDD '12). ACM, New York, NY, USA, 289-297.'.
