InverseFeatureScaling

Apply the inverse of feature scaling to one or more sample(s). [fA, fB] should be used if the scaling has been performed using TCVN_FST1_MINMAX with a predetermined output range..

Syntax

Definition:

HRESULT InverseFeatureScaling(
    HRESULT          hrPrev,
    ITcVnContainer*  ipSamples,
    ITcVnContainer*  ipScales,
    ITcVnContainer*& ipInverseSamples,
    double           fA = 0.0,
    double           fB = 1.0
)

Parameters

Name

Type

Default

Description

hrPrev

HRESULT

 

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

ipSamples

ITcVnContainer*

 

Container holding one or more input sample(s) (ContainerType_Vector_REAL, ContainerType_Vector_LREAL, ContainerType_Vector_Vector_REAL, or ContainerType_Vector_Vector_LREAL)

ipScales

ITcVnContainer*

 

Container with the scaling parameters of each feature (type ContainerType_Vector_REAL or ContainerType_Vector_LREAL).

ipInverseSamples

ITcVnContainer*&

 

Returns the inversed sample(s) using the scaling type and parameters of ipScales. It has the same type of ipSamples. If the same container ipSamples is used, the source data will be replaced.

fA

double

0.0

represents the lower bound of the range for TCVN_FST1_MINMAX

fB

double

1.0

represents the upper bound of the range for TCVN_FST1_MINMAX
