dc.description.abstract | This brief presents a piecewise linear approximation
of the nonlinear Wilson (NW) neuron model for the realization
of an efficient digital circuit implementation. The accuracy
of the proposed piecewise Wilson (PW) model is examined by
calculating time domain signal shaping errors. Furthermore,
bifurcation analyses demonstrate that the approximation follows
the same bifurcation pattern as the NW model. As a
proof of concept, both models are hardware synthesized and
implemented on field programmable gate arrays, demonstrating
that the PW model has a range of neuronal behaviors similar
to the NW model with considerably higher computational
performance and a lower hardware overhead. This approach can
be used in hardware-based large scale biological neural network
simulations and behavioral studies. The mean normalized root
mean square error and maximum absolute error of the PW
model are 6.32% and 0.31%, respectively, as compared to the
NW model. | es |
