In this paper, we describe a prototype speaker identification system using auto-associative neural network (AANN) and formant features. Our experiments demonstrate that formants extracted from difference spectrum perform significantly better than formants extracted from normal spectrum for the task of speaker identification. We also demonstrate that(More)
This paper presents zero suffix method for solving the classical symmetric traveling salesman problem (TSP). It is conjectured that the chance of improving a good solution by moving a node to a position far away from its original one is small, it is possible to further improve a TSP tour that cannot be improved by other local search methods. To test the(More)
