java.lang.Object org.opencv.ml.CvANN_MLP_TrainParams
public class CvANN_MLP_TrainParams
Parameters of the MLP training algorithm. You can initialize the structure by a constructor or the individual parameters can be adjusted after the structure is created.
The back-propagation algorithm parameters:
Strength of the weight gradient term. The recommended value is about 0.1.
Strength of the momentum term (the difference between weights on the 2
previous iterations). This parameter provides some inertia to smooth the
random fluctuations of the weights. It can vary from 0 (the feature is
disabled) to 1 and beyond. The value 0.1 or so is good enough
// C++ code:
The RPROP algorithm parameters (see [RPROP93] for details):
Initial value Delta_0 of update-values Delta_(ij).
Increase factor eta^+. It must be >1.
Decrease factor eta^-. It must be <1.
Update-values lower limit Delta_(min). It must be positive.
Update-values upper limit Delta_(max). It must be >1.

public CvANN_MLP_TrainParams()
The constructors.
By default the RPROP algorithm is used:
// C++ code:
CvANN_MLP_TrainParams.CvANN_MLP_TrainParams()
term_crit = cvTermCriteria(CV_TERMCRIT_ITER + CV_TERMCRIT_EPS, 1000, 0.01);
train_method = RPROP;
bp_dw_scale = bp_moment_scale = 0.1;
rp_dw0 = 0.1; rp_dw_plus = 1.2; rp_dw_minus = 0.5;
rp_dw_min = FLT_EPSILON; rp_dw_max = 50.;
