Method Detail

functionValue

public double functionValue()

Overrides:

functionValue in class Function

hasAnalyticalVariableGradient

public boolean hasAnalyticalVariableGradient(Variable var)

Description copied from class: Function

To be overwritten by classes extending Function. This method is used internally by this class to determine if a function has can provide an analytical gradient with respect to a given Variable.

Overrides:

hasAnalyticalVariableGradient in class Function

evaluateAnalyticalVariableGradient

public double evaluateAnalyticalVariableGradient(Variable var)

Description copied from class: Function

To be overwritten by classes extending Function. This method is used internally by this class to evaluate the derivative with respect to a given Variable.

Overrides:

evaluateAnalyticalVariableGradient in class Function

hasAnalyticalNormalization

public boolean hasAnalyticalNormalization(Dependent dep)

Description copied from class: Function

To be overwritten if Function provides analytical normalization.

Overrides:

hasAnalyticalNormalization in class Function

evaluateAnalyticalNormalization

public double evaluateAnalyticalNormalization(Dependent dep)

Overrides:

evaluateAnalyticalNormalization in class Function

updateNormalization

protected void updateNormalization()

Overrides:

updateNormalization in class Function
