Class TimeSeriesForestClassifier

  • public class TimeSeriesForestClassifier
extends ASimplifiedTSClassifier<java.lang.Integer>
    Time series forest classifier as described in Deng, Houtao et al. "A Time Series Forest for Classification and Feature Extraction." Inf. Sci. 239 (2013): 142-153. Consists of mutliple TimeSeriesTreeClassifier classifier. This classifier only supports univariate time series prediction.
