setFieldDefs
Set the field definitions for this Expression to use- 覆盖:
setFieldDefs
在类中Expression
- 参数:
fieldDefs
- the field definitions to use- 抛出:
Exception
- if there is a problem setting the field definitions
-
getResult
Get the result of evaluating the expression. In the case of a continuous optype, a real number is returned; in the case of a categorical/ordinal optype, the index of the nominal value is returned as a double.- 指定者:
getResult
在类中Expression
- 参数:
incoming
- the incoming parameter values- 返回:
- the result of normalizing the input field
- 抛出:
Exception
- if there is a problem computing the result
-
getResultInverse
public double getResultInverse(double[] incoming) Compute the inverse of the normalization (i.e. map back to a unormalized value).- 参数:
incoming
- the incoming parameter values- 返回:
- the unormalized value
-
getResultCategorical
Always throws an Exception since the result of NormContinuous must be continuous.- 指定者:
getResultCategorical
在类中Expression
- 参数:
incoming
- the incoming parameter values- 返回:
- the result of evaluating the expression
- 抛出:
Exception
- always
