Simulation of CIRP nosof88 with ex-ALCOVE model
Runs a simulation of the
nosof88 CIRP using the
slpALCOVE model implementation as an exemplar model and
nosof88train as the input representation.
A vector containing values for c, phi, la, and lw, in
that order. See
An exemplar-based simulation using
nosof88train. The co-ordinates for the radial-basis units
are taken from the multdimensional scaling solution for these stimuli
reported by Nosofsky (1987).
The defaults for
params are the best fit of the model to the
nosof88 CIRP. They were derived through minimization of
SSE using non-linear optimization from 16 different initial
states (using code not included in this archive).
The 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
nosof88exalcove function, and hence can't be changed
without re-writing the function.
