SnnsRObject$somPredictCurrPatSetWinners: Get most of the relevant results from a som
Description
SnnsR low-level function to get most of the relevant
results from a SOM.Usage
## S3 method for class 'SnnsR':
somPredictCurrPatSetWinners(updateFuncParams=c(0.0,
0.0, 1.0), saveWinnersPerPattern=TRUE, targets=NULL)Arguments
updateFuncParams
parameters passed to the networks
update function
saveWinnersPerPattern
should a list with the
winners for every pattern be saved?
targets
optional target classes of the patterns
Value
- a list with three elements:
- nWinnersPerUnitFor
each unit, the amount of patterns where this unit won is
given. So, this is a 1d vector representing the normal
version of the som.
- winnersPerPatterna vector
where for each pattern the number of the winning unit is
given. This is an intermediary result that normally won't
be saved.
- labeledUnitsa matrix which -- if the
targets parameter is given -- contains for each
unit (rows) and each class present in the targets
(columns), the amount of patterns of the class where the
unit has won. From the labeledUnits, the
labeledMap can be computed, e.g. by voting of the
class labels for the final label of the unit.
