kohonen.SDA {symbolicDA}

Kohonen's self-organizing maps for symbolic interval-valued data

Description

Kohonen's self-organizing maps for a set of symbolic objects described by interval-valued variables

Usage

kohonen.SDA(data, rlen=100, alpha=c(0.05,0.01))

Arguments

data

symbolic data table in simple form (see SO2Simple)

rlen

number of iterations (the number of times the complete data set will be presented to the network)

alpha

learning rate, determining the size of the adjustments during training. Default is to decline linearly from 0.05 to 0.01 over rlen updates

Details

See file ../doc/kohonenSDA_details.pdf for further details

Value

clas

vector of mini-class belonginers in a test set

prot

prototypes
