Solution for the XOR problem are formulated by normal vectors orthogonal to separation hyperplanes when nonlinear units are given by threshold functions. The shapes of solution regions are shown to be different for bipolar and unipolar nets. This suggests that attractors for BP leaning depend on polarity.
