证明了齐次性和对称性是三层前向网络检察平移不变性和旋转不变性的充分条件。例证了权值为同心圆结构的感受野型三层前向网络是T-C问题的一个解案。从理论上说明视觉系统中同心圆结构感受野的合理性。
It is proved that homogeneity and symmetry are sufficient conditions for the translational invariance and rotation invariance of the three-layer forward-looking network prosecution. An example is given to illustrate that the receptive field-type three-layer forward network with concentric concentric weights is a solution to the T-C problem. The rationality of the receptive fields of concentric circles in the visual system is theoretically explained.
