Neural complex (real or artificial) which is an embodiment of massivel
y connected set of neurons represents a cellular automaton ''trained t
o learn'' and predict via endeavours managed by a set of protocols inv
olving collection, conversion, transmission, storage and retrieval of
information. The training or the learning effort is to recognize and c
ounter-balance the effects of the cellular disturbances (noise) presen
t in the neural system which may tend to disorganize the system's conv
ergence towards an objective function (mediated through learning proto
cols). The extent of disorganization caused by such disturbances can b
e specified by a disorderliness parameter set by the maximum entropy c
onsiderations. Such an entropy functional depicts implicitly the degre
e of complexity of the system (in spatiotemporal domains) as well. The
refore, the disorderliness in the neural complex can be specified by a
complexity metric. Using this metric-parameter as an error-measure (o
r cost-function), a control strategy (such as the backpropagation base
d gradient-descent method) can be developed to train a multilayered pe
rceptron. Present study offers relevant algorithmic considerations and
simulation results.
