The subclasses of theses class use unbounded target values. These are for example the number of steps or the number of learned episodes. For unbounded target values you can define an offset and a scale value for the target (Parameters: "APTargetMin", "APTargetMax"). The target value is then transformed the following way x = target_offset + target_scale * target. After the transformation the function defined by the parameter "APFunctionKind" gets applied. The 6 different functions are calucalated the following way: LINEAR: f(x) = x SQUARE: f(x) = x^2 LOG: f(x) = log(x + 1.0) FRACT: f(x) = (1.0 / (x + 1.0)) FRACTSQUARE: f(x) = (1.0 / (x^2 + 1.0) FRACTLOG : f(x) = 1.0 / (1.0 + log(x + 1.0)); The result can be now again scaled and an offset can be added ("APParamScale", "APParamOffset"), so the resulting parameter value is calculated with the formular param = param_offset + param_scale * f(transformed_targetvalue). These gives you much degree of freedom to design your adaptive parameter calculator. The values of the parameters "APParamScale", "APParamOffset", APTargetMin" and "APTargetMax" are again stored in own data element for performance reasons and updated by the function onParameterChanged. See the subclasses for the different target values. Parameters of CAdaptiveParameterBoundedValuesCalculator: "APFunctionKind": Defining the function to transform target value into the parameter value. "APParamScale": Scale of the parameter value "APParamOffset": Parameter Value offset "APTargetScale": Scale value of the target "APTargetOffset": Offset value of the target Constructor & Destructor Documentation CAdaptiveParameterUnBoundedValuesCalculator::CAdaptiveParameterUnBoundedValuesCalculator (  CParameters *  targetObject, string  targetParameter, int  functionKind, double  param0, double  paramScale, double  targetOffset, double  targetScale )  virtual CAdaptiveParameterUnBoundedValuesCalculator::~CAdaptiveParameterUnBoundedValuesCalculator (   )  [virtual] Member Function Documentation virtual void CAdaptiveParameterUnBoundedValuesCalculator::onParametersChanged (   )  [virtual]   Updates all data elements which represents parameters. Reimplemented from CAdaptiveParameterCalculator. Reimplemented in CAdaptiveParameterFromNStepsCalculator, and CAdaptiveParameterFromNEpisodesCalculator. virtual void CAdaptiveParameterUnBoundedValuesCalculator::setParameterValue (  double  value  )  [virtual]   Returns the value of the parameter. The value of the parameter is calculated the follwing way: param = param_offset + param_scale * f(target_offset + target_scale * target) For more details see class description.
