Abstract(in English) | It is difficult to introduce appropriate activation functions to neural networks in the hypercomplex domains, and few functions have been developed so that bounded and analytic (differentiable) conditions are satisfied, as compared with the activation functions in real-valued neural networks. This paper proposes a Hopfield-type neural network on quaternion which is a class of hypercomplex number systems. The activation function in the proposed network is an extension of tanh function in the complex domain with introducing local analyticiy. The stability conditions of this network is also shown by proving monotonic decrease of energy for the network with respect to the changes of neuron states. |
