sampleClassif: sampleClassif

Description Usage Arguments Value Author(s) See Also Examples

Description

performs task analogous to mixKnn (i.e. leave-one-out classification), but uses synthetic representatives to infer labels, instead of k-NN. Each representative is obtained by concatenating all GMM (i.e. elements) of a specific label value, resampling from this redundant mixture, and applying varbayes on this sample.

Usage

1
sampleClassif(data, labels, KLparam = 500, rho = new.env())

Arguments

data

list of GMM.

labels

vector of numeric labels associated to data.

KLparam

number of samples for jsmc.

rho

R environment object. Used to issue R commands within the C routine.

Value

classification error ratio in [0,1].
