This paper proposes a novel multilayer feedforward quaternion neural network (RQN) model architecture, and aims to clearly elucidate its learning characteristics. While previous research on quaternion neural networks has been applied to various fields, there has been no research on the characteristics of multilayer feedforward quaternion neural networks with weights applied in the reverse direction. In this paper, we investigate the learning characteristics of RQNs from two perspectives: learning speed and generalization to rotations. As a result, we found that RQNs have a learning speed comparable to existing models and can obtain rotation representations different from existing models.
