  • 构造器详细资料

    • DNConditionalEstimator

      public DNConditionalEstimator(int numSymbols, double precision)
      Constructor
      参数:
      numSymbols - the number of symbols
      precision - the precision to which numeric values are given. For example, if the precision is stated to be 0.1, the values in the interval (0.25,0.35] are all treated as 0.3.
