| Abstract(in English) | A complex-valued neural network can be used for multistate associative memory by quantizing a neuronal state into a multivalued state with an appropriate threshold function. The complex-signum function used in conventional multistate associative memory models is a transformation including a multilevel signum function in essence. In the present report, we propose a complex-valued threshold function based on nonlinear multilevel functions and show the recall performance of the multistate associative memory based on the proposed method. Numerical experiments clarify how the recall capability is influenced by the parameter controlling the nonlinearity of the multilevel function, the number of the stored patterns, and the number of quantized states. We also demonstrate gray-level image reconstruction with the proposed method. |
