| Abstract(in English) | This paper formulates a separability condition by normal vectors so that the separation hyperplanes should pass through a rectangle surrouding the input set. Then it depicts the distributions of two-dimensional normal vectors satisfying the condition. These distributions elucidate that the condition for the first hidden layer varies significantly even if the input patterns are simply translated, and that those conditions (in a wider sense) for the other layers are different between unipolar and bipolar units. It, also depicts an initial distribution of normal vectors with the weights initialized ordinarily by random values with zero mean. Comparison of the initial distribution to the separability condition leads to the fact that the bipolar net is superior to the unipolar net in convergence of the back propagation learning initialized randomly in such an ordinary manner. The bipolar nets exhibit better convergence than the unipolar nets even if their input space divisions in every layer by the separation hyperplanes are geometrically the same at the outset of the learning. |
