APPARATUS FOR PATTERN RECOGNITION.

摘要

PCT No. PCT/GB88/00710 Sec. 371 Date May 9, 1989 Sec. 102(e) Date May 9, 1989 PCT Filed Aug. 26, 1988 PCT Pub. No. WO89/02134 PCT Pub. Date Mar. 9, 1989.A temporal sequence of signal vectors X (e.g., generated from a speech signal) is supplied in parallel to elements in an array each of which (after training of the array) provide an output eta indicating the vector's similarity to a reference vector. Persistence is built into the elements so that signals forming a "trajectory" within the array, corresponding to an input sequence are simultaneously available for recognition (preferably by a further such array). Arrays may be cascaded to allow for longer sequences.
