BPROJ Backward Projection using the SOM
[pr,res,bmu] = bproj(g,smap,projtype)
g: (Rout x Q) vector in the output space with data points by columns
smap: SOM struct (see INISOM, BSOM)
projtype: String with the projection type:
'discrete: Original discrete SOM projection (default)
'grnn': Generalized Regression Neural Network
'ls': Uses seast squares (Ridge Regression) to compute
the weight matrix
CALLS
[pr,res,bmu] = bproj(p,smap)
[pr,res,bmu] = bproj(p,smap,projtype)
DESCRIPTION
Projects output space samples (given as columns of data matrix g) onto
the input space using the projection defined by the som 'smap'. Projection
can be either discrete or continuous.
