| Abstract(in English) | This paper studies a bi-objective optimization problem in a binary associative memories(BAMs). The BAMs are characterized by ternary cross-connection parameters and the signum activation function. In order to define the problem, we introduce two objectives: the first objective evaluates direct stability of the desired memories and the second objective evaluates connection sparsity. In order to solve the biobjective optimization problem, we apply an evolutionary algorithm. Performing precise numerical experiments for simple examples of the BAMs, we have confirmed existence of trade-offs between the two objectives. |
