Topological map computation system and method in which the continuity of changes in input patterns is considered

摘要

In a computation system for a topological map, a winner-unit-candidate-set calculation module calculates a winner unit candidate set which is the set of candidates for a winner unit corresponding to an input vector at a current input timing, on the topological map. The calculation module calculates the winner unit candidate set on the basis of, for example, a winner unit having been calculated at a past input timing near the current input timing. A winner-unit calculation module calculates the winner unit which corresponds to the input vector at the current input timing, as the unit which has received the maximum input among the units contained in the winner unit candidate set calculated by the winner-unit-candidate-set calculation module.
