Discontinuity and Complex Dynamics of Neural Networks
Zhou Changsong, Chen Tian-Lun · Communications in Theoretical Physics · 1998
We focus on the discontinuity of a neural network model with diluted and clipped synaptic connections ( only). The exact evolution rule of the average firing rate becomes a discontinuous piece-wise nonlinear map when very simple functions of dynamical threshold are introduced into the network. Complex dynamics is observed.
