java.lang.Object

org.ai_heuristic.functs.Function

org.ai_heuristic.functs.FunctionSingle

org.ai_heuristic.functs.FunctionActivate

All Implemented Interfaces:

FunctionDef, FunctionSingleDef

Direct Known Subclasses:

FunctionHardLimit, FunctionLinear, FunctionLinearPlus, FunctionLinearRectified, FunctionSigmoid, FunctionSymmetricHardLimit, FunctionTanH

public abstract class FunctionActivate
extends FunctionSingle

This is the base class for any of the activation functions that measure a value against a threshold. The evaluate method that gets implemented should probably return a Double value.

Constructor Detail

FunctionActivate

public FunctionActivate()
                 throws java.lang.Exception

Create a new instance of FunctionActivate. The eval evaluator is set to SimpleMathCompare. To change this, use the setEvaluator method.

Throws:

java.lang.Exception - any error.

FunctionActivate

public FunctionActivate(java.lang.String thisValueType)
                 throws java.lang.Exception

Create a new instance of FunctionActivate. The eval evaluator is set to SimpleMathCompare. To change this, use the setEvaluator method.

Parameters:

thisValueType - the type of object being evaluated. Can be null if set later or not used.

Throws:

java.lang.Exception - any error.

FunctionActivate

public FunctionActivate(java.lang.String thisValueType,
                        java.util.HashMap<java.lang.String,?> thisConfig)
                 throws java.lang.Exception

Create a new instance of FunctionActivate. The eval evaluator is set to SimpleMathCompare. To change this, use the setEvaluator method.

Parameters:

thisValueType - the type of object being evaluated. Can be null if set later or not used.

thisConfig - list of initialisation function-specific parameters.

Throws:

java.lang.Exception - any error.
