// // should be kept for good reconstruction capabilities. It is based on your input data,
// // so experiment with the number. Keeping 80 components should almost always be sufficient.
// //
// // threshold – The threshold applied in the prediciton. This still has issues as it work inversly to LBH and Fisher Methods.
// // if you use 0.0 recognizer.Predict will always return -1 or unknown if you use 5000 for example unknow won't be reconised.
// // As in previous versions I ignore the built in threhold methods and allow a match to be found i.e. double.PositiveInfinity
// // and then use the eigen distance threshold that is return to elliminate unknowns.

// //NOTE: The following causes the confusion, sinc two rules are used.
