      Modifier and Type Method Description
      double[] alphabet()
      The alphabet consists of doubles representing letters and defines each word.
      int alphabetSize()
      The alphabet size determines the number of Bins for the SFA Histograms.
      boolean meanCorrected()
      If mean corrected is set to true than the first DFT coefficient is dropped to normalize the mean.
      int windowSize()
      The size of the sliding window that is used over each instance and splits it into multiple smaller instances.
      int wordLength()
      The word length determines the number of used DFT-coefficients.

    • Method Detail

      • windowSize

        @Key("boss.windowsize")
int windowSize()
        The size of the sliding window that is used over each instance and splits it into multiple smaller instances.

      • alphabetSize

        @Key("boss.alphabetsize")
@DefaultValue("4")
int alphabetSize()
        The alphabet size determines the number of Bins for the SFA Histograms. Four was determined empirical as an optimal value for the alphabet size. cf.p. 1519 "The BOSS is concerned with time series classification in the presence of noise by Patrick Schäfer"

      • alphabet

        @Key("boss.alphabet")
double[] alphabet()
        The alphabet consists of doubles representing letters and defines each word.

      • wordLength

        @Key("boss.wordlength")
int wordLength()
        The word length determines the number of used DFT-coefficients. Where the DFT-coefficients are half the word length.

      • meanCorrected

        @Key("boss.meancorrected")
boolean meanCorrected()
        If mean corrected is set to true than the first DFT coefficient is dropped to normalize the mean. c.f.p. 1519 "The BOSS is concerned with time series classification in the presence of noise by Patrick Schäfer"
