      • EPSILON_ID

        public static final OptionID EPSILON_ID
        Parameter to specify the maximum distance between two vectors with equal preference vectors before considering them as parallel, must be a double equal to or greater than 0.

      • ALPHA_ID

        public static final OptionID ALPHA_ID
        The maximum absolute variance along a coordinate axis. Must be in the range of [0.0, 1.0).

      • DEFAULT_ALPHA

        public static final double DEFAULT_ALPHA
        The default value for alpha.

      • K_ID

        public static final OptionID K_ID
        The number of nearest neighbors considered to determine the preference vector. If this value is not defined, k is set to three times of the dimensionality of the database objects.

      • alpha

        protected double alpha
        The maximum absolute variance along a coordinate axis.

      • k

        protected int k
        The number of nearest neighbors considered to determine the preference vector.

      • configure

        public void configure​(Parameterization config)
        Description copied from interface: Parameterizer
        Configure the class.

        Note: the status is collected by the parameterization object, so that multiple errors may arise and be reported in one run.

        Specified by:
        configure in interface Parameterizer
        Parameters:
        config - Parameterization

      • make

        public HiSC make()
        Description copied from interface: Parameterizer
        Make an instance after successful configuration.

        Note: your class should return the exact type, only this very broad interface should use Object as return type.

        Specified by:
        make in interface Parameterizer
        Returns:
        a new instance
