“…Several synthesis procedures have been developed for designing symmetric and non‐symmetric neural network (Michel and Farrell, 1988; Liu and Michel, 1993; Park and Park, 2000). Besides synthesis methods, increased attention is also being paid lately on the issue of stability in the dynamic behavior of these systems in the presence of time delays (Arik and Tavsanoglu, 2005; Park, 2006, 2008; Kao and Gao, 2008; Zeng et al , 2008), typically addressed in the context of Lyapunov‐Krasovksii functionals, and linear matrix inequalities (LMIs) formulated based on bounds related to these delays. This particular research direction, however, falls outside the scope of this paper, since the patterns we are interested in identifying are static.…”
