public float predict(Mat samples)
Predicts the response for sample(s).
The method estimates the most probable classes for input vectors. Input
vectors (one or more) are stored as rows of the matrix samples.
In case of multiple input vectors, there should be one output vector
results. The predicted class for a single input vector is
returned by the method.
The function is parallelized with the TBB library.

Trains the model.
The method trains the Normal Bayes classifier. It follows the conventions of the generic "CvStatModel.train" approach with the following limitations:
CV_ROW_SAMPLE data layout is supported.
responses must be integer numbers, though the vector may have
the CV_32FC1 type.

(update=false) or should be updated using the new training data
(update=true).
