understanding of cortical dynamics. This encompasses
corticonics (echoing electronics), neural networks;
complexity, and dynamical computing with diverse
attractors, the role of synchronization, bifurcation, and
chaos in computing and encryption; holographic models of
cortical information processing; biomorphic and
bifurcation networks for feature extraction, feature
binding and cognition; hardware (optoelectronic)
implementation of bifurcation processing elements and
networks. Image understanding and neuromorphic signal
processing; remote sensing and automated object and radar
target recognition.
Past
Microwave diversity imaging and optical information
processing employing spectral, angular and polarization
degrees of freedom; Image understanding and tomography;
Optoelectronic neural networks, Stochastic learning and
optical Boltzmann machines.
