getGuess

public Distribution getGuess(DataSet data)

This method allows one to obtain a distribution that represents a reasonable "guess" at the range of values that would work for this parameter. If the DataSet is an instance of ClassificationDataSet or RegressionDataSet, the method may choose to assume that the value is being guessed for the specified task and change its behavior

Providing a getGuess is not required, and returns null if guessing is not supported.

Parameters:

data - the data with which we want a reasonable guess for this parameter

Returns:

a distribution that represents a reasonable guess of a good value for this parameter given the input data

getValueString

a string representation of the parameter's value
