Synthesis of a Cellular Nonlinear Network for a Fuzzy Associative Memory in Stereoscopic Vision
No full textIn this paper a Cellular Fuzzy Associative Memory containing fuzzy rules for gray image fuzzification is designed, considered as a subsystem of a CNN-based architecture able to store bidimensional patterns. After establishing the fuzzy rules which characterize the required FAM, these rules are properly codified and stored in a Cellular Nonlinear Network behaving as a memory. A numerical example concerning with the stereoscopic vision of a mobile robot is reported to show how the synthesized memory can process bidimensional patterns for robotic vision purposes
Associative Memory Design using Discrete-time Second-Order Neural Networks with Local Interconnections
No full textIn this brief a design method for associative memories using a new model of discrete-time high-order neural networks which includes local interconnections among neurons is illustrated. The synthesis approach, which exploits the properties of pseudoinverse matrices, reveals flexible as it enables to choose the complexity of the associative memory to be designed that is, it can generate networks for associative memories with first-order and/or higher order interactions among neurons. The suggested technique preserves local interconnections among neurons, making feasible an implementation of such networks. Simulation results and comparisons among different neural architectures are reported to show the applicability of the proposed method
Heteroassociative Memories via Cellular Neural Networks
No full textIn this paper a synthesis procedure for heteroassociative memories using Cellular Neural Networks (CNNs) is presented. The suggested method, by assuring the condition of symmetry of the interconnection matrix, guarantees the complete stability of the designed network, besides providing that all the stored patterns correspond to asymptotically stable equilibrium points. Numerical examples are carried out to show the behaviour of the designed memory with respect to input perturbations. Moreover, the storage capacity and the presence of spurious equilibria have been investigate
