A continuous-time network with piecewise linear neuron input-output characteristics is proposed for optimization applications. Certain qualitative properties of the network of fundamental importance in these applications, such as the uniqueness of equilibrium conditions and the global exponential stability with any arbitrarily prescribed degree of this equilibrium, are analytically investigated. Deriving guidance from the obtained analytical results, a systematic synthesis procedure is outlined for identifying the network parameters and the bias inputs to employ the neural network for efficiently solving the important class of optimization problems where the objective is to minimize a specified quadratic function in the decision variables. For demonstrating the versatility of the solution procedure, three illustrative applications, namely synthesis of a class of spatial filters popularly employed in image recognition, the design of an associative memory by a master-slave formulation and the estimation of parameters of a linear system by a least squares procedure are outlined and the superiority of the present approach over the existing results is indicated. Some of the present results concerning the characterization of the network equilibrium conditions and the network scaling for confining the equilibrium to desired operational ranges are of basic interest and are useful in other applications of the neural network besides the specific applications to solve optimization problems discussed in this paper. |
