Redundancy of the parameters of the complex-valued neural network

Abstract

In this letter, we will clarify the redundancy of the parameters of the complex-valued neural network. The results may be summarized as follows. There exist the four transformations which can cause the redundancy of the parameters of the complex-valued neural network, including the two transformations which can cause the redundancy of the parameters of the real-valued neural network (i.e., the interchange of the two hidden neurons and the sign flip of the parameters on the hidden neurons).
