When patterns are stored by using associative learning in a chaotic ne
ural network consisting of chaotic neurons that easily produces chaos,
whether dynamic (chaotic) or static (non-chaotic) remembering occurs
can be controlled by varying the parameters of the chaotic neurons. A
pattern can be searched by using this dynamic remembering as a samplin
g procedure. If features of the output pattern of the network become s
imilar to desired features during the search, the chaotic state is cha
nged to a static remembering state so that the output pattern has desi
red features. In this paper, the state is controlled by using a model
of presynaptic inhibition similar to that seen in real nerve cells (no
t using the parameters of the chaotic neurons). Extraction and compari
son of the features are performed by back-propagation networks. The ex
traction of features under this method is amenable to visual represent
ation of its trajectory in feature space.
