Parameters
model (IntPtr)
The Decision Tree model
trainData (IntPtr)
The training data. A 32-bit floating-point, single-channel matrix, one vector per row
tflag (DATA_LAYOUT_TYPE)
The data layout type of the train data
responses (IntPtr)
A floating-point matrix of the corresponding output vectors, one vector per row.
varIdx (IntPtr)
Can be IntPtr.Zero if not needed. When specified, identifies variables (features) of interest. It is a Matrix>int< of nx1
sampleIdx (IntPtr)
Can be IntPtr.Zero if not needed. When specified, identifies samples of interest. It is a Matrix>int< of nx1
varType (IntPtr)
The types of input variables
missingMask (IntPtr)
Can be IntPtr.Zero if not needed. When specified, it is an 8-bit matrix of the same size as trainData, is used to mark the missed values (non-zero elements of the mask)
param (MCvDTreeParams)
The parameters for training the decision tree
