Runs a simulation of the
nosof88 CIRP using the
slpALCOVE model implementation as a prototype model and
nosof88train as the input representation.
nosof88protoalcove(params = NULL)
A vector containing values for c, phi, la, and lw, in
that order, e.g. params = c(2.1, 0.6, 0.09, 0.9). See
An prototype-based simulation using
nosof88train. There is one radial-basis unit for each
category, representing the prototype. These prototypes are calculated
by taking the mean of the co-ordinates of the stimuli in a category,
with the stimulus co-ordinates coming from the multdimensional
scaling solution reported by Nosofsky (1987). The calculations of the
means are weighted by the instantiation frequency of the
stimuli. Hence, the prototypes for each condition of the experiment
Other parameters of slpALCOVE are set as follows:
r = 2,
q = 1, initial
alpha = 1 / (number of input dimensions),
w = 0. These values are conventions of modeling with
ALCOVE, and should not be considered as free parameters. They are set
nosof88protoalcove function, and hence can not be
changed without re-writing the function.
