Parameters

trainData
Matrix<(Of <(<'Single>)>)>
The training data. A 32-bit floating-point, single-channel matrix, one vector per row
responses
Matrix<(Of <(<'Single>)>)>
A floating-point matrix of the corresponding output vectors, one vector per row.
sampleIdx
Matrix<(Of <(<'Byte>)>)>
Can be null if not needed. When specified, identifies samples of interest. It is a Matrix>int< of nx1
isRegression
Boolean
Specify the output variables type. It can be either categorical (isRegression=false) or ordered (isRegression=true)
maxK
Int32
The number of maximum neighbors that may be passed to the method findNearest.
updateBase
Boolean
If true, the existing classifer is updated using the new training data; Otherwise, the classifier is trained from scratch
