DiscreteEstimator
public DiscreteEstimator(int numSymbols, boolean laplace) Constructor- 参数:
numSymbols
- the number of possible symbols (remember to include 0)laplace
- if true, counts will be initialised to 1
-
DiscreteEstimator
public DiscreteEstimator(int nSymbols, double fPrior) Constructor- 参数:
nSymbols
- the number of possible symbols (remember to include 0)fPrior
- value with which counts will be initialised
