Spherical Units can be used to construct dynamic reconfigurable consequential regions, the geometric bases for Shepard's (1987) theory of stimulus generalization in animals and humans. We derive from Shepard's (1987) generalization theory a particular multi-layer network with dynamic (centers and radii) spherical regions which possesses a specific mass function (Cauchy). This learning model gen...

The feeling of the national identity is fixing the differences “our – strangers”, “ours – not ours”. When the ethnic culture is formed there is an intensive process of self-reflection, self-identification, “the image of yourself” is made up in relation to the “images” of other people, c...
