"In human cognition, the expansion of perceived between-category distances and\ncompression of within-category distances is known as categorical perception\n(CP). There are several hypotheses about the causes of CP (e.g., language,\nlearning, evolution) but no functional model. Whether CP is essential to\ncategorisation or simply a by-product of it is not yet clear, but evidence is\naccumulating that CP can be induced by category learning. We provide a model\nfor learning-induced CP as expansion and compression of distances in\nhidden-unit space in neural nets. Basic conditions from which the current model\npredicts CP are described, and clues as to how these conditions might\ngeneralize to more complex kinds of categorization begin to emerge."
