      • EPSILON_ID

        public static final OptionID EPSILON_ID
        Parameter to specify the maximum radius of the neighborhood to be considered, must be suitable to the distance function specified.

      • MINPTS_ID

        public static final OptionID MINPTS_ID
        Parameter to specify the threshold for minimum number of points in the epsilon-neighborhood of a point, must be an integer greater than 0.

      • epsilon

        protected double epsilon
        Holds the epsilon radius threshold.

      • minpts

        protected int minpts
        Holds the minimum cluster size.

      • distance

      • 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 DBSCAN<O> 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
