Class CvANN_MLP_TrainParams

java.lang.Object
  org.opencv.ml.CvANN_MLP_TrainParams

public class CvANN_MLP_TrainParams
extends java.lang.Object

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.

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.;
