PARZENM Trainable mapping for estimating Parzen densities
W = PARZENM(A,H) D = B*W
DescriptionA Parzen distribution is estimated for the labeled objects in A. Unlabeled objects are neglected, unless A is entirely unlabeled or double. Then all objects are used. If A is a multiclass dataset the densities are estimated class by class and then weighted and combined according to their prior probabilities. In all cases, just a single density estimator W is computed. The mapping W may be applied to a new dataset B using DENSITY = B*W. The smoothing parameter H is estimated by PARZENML if not supplied. It can be a scalar or a vector with as many components as A has features. Note that PARZENML my may be stopped prematurely by PRTIME. Example(s)prex_density, for, densities, and, prex_parzen, for, differences, between, PARZENC, PARZENDC and PARZENM.
