    • Field Detail

      • ALPHA_THRESHOLD_ID

        public static final elki.utilities.optionhandling.OptionID ALPHA_THRESHOLD_ID
        Parameter for the chi squared test threshold.

      • POISSON_THRESHOLD_ID

        public static final elki.utilities.optionhandling.OptionID POISSON_THRESHOLD_ID
        Parameter for the poisson test threshold.

      • MAX_EM_ITERATIONS_ID

        public static final elki.utilities.optionhandling.OptionID MAX_EM_ITERATIONS_ID
        Maximum number of iterations for the EM step.

      • EM_DELTA_ID

        public static final elki.utilities.optionhandling.OptionID EM_DELTA_ID
        Threshold when to stop EM iterations.

      • MIN_CLUSTER_SIZE_ID

        public static final elki.utilities.optionhandling.OptionID MIN_CLUSTER_SIZE_ID
        Minimum cluster size for noise flagging. (Not existant in the original publication).

      • alpha

        protected double alpha
        Parameter for the chi squared test threshold. While statistical values such as 0.01 are a good choice, we found the need to modify this parameter in our experiments.

      • poissonThreshold

        protected double poissonThreshold
        Parameter for the poisson test threshold.

      • maxEmIterations

        protected int maxEmIterations
        Maximum number of iterations for the EM step.

      • emDelta

        protected double emDelta
        Threshold when to stop EM iterations.

      • minClusterSize

        protected int minClusterSize
        Minimum cluster size for noise flagging. (Not existant in the original publication).
