Nonlinear Dynamics and Chaos in Fractional-Order Hopfield Neural Networks with Delay
Xia Huang, Zhen Wang, Yuxia Li · Advances in Mathematical Physics · 2013
A fractional-order two-neuron Hopfield neural network with delay is proposed based on the classic well-known Hopfield neural networks, and further, the complex dynamical behaviors of such a network are investigated. A great variety of interesting dynamical phenomena, including single-periodic, multiple-periodic, and chaotic motions, are found to exist. The existence of chaotic attractors is verified by the bifurcation diagram and phase portraits as well.
