KernelPrincipalComponentAnalysisRevert Method (Double, Int32)

Note: This API is now obsolete.

Reverts a set of projected data into it's original form. Complete reverse transformation is not always possible and is not even guaranteed to exist.

Namespace: Accord.Statistics.Analysis
Assembly: Accord.Statistics (in Accord.Statistics.dll) Version: 3.8.0

Parameters

data: Type: SystemDouble
The kpca-transformed data.
neighbors: Type: SystemInt32
The number of nearest neighbors to use while constructing the pre-image.

Return Value

Type: Double

Remarks

This method works using a closed-form MDS approach as suggested by Kwok and Tsang. It is currently a direct implementation of the algorithm without any kind of optimization.
