Claim 5:
6. The method according to claim 5, wherein, before the residual vector corresponding to the each piece of second data is obtained based on the residual between the each piece of second data and the first-level cluster center closest to the piece of second data and the residual between the each piece of second data and the second-level cluster center closest to the second data, the method further comprises:
calculating a distance from the each piece of second data to the first-level cluster center and a distance from the each piece of second data to the second-level cluster center; and
determining the first-level cluster center closest to the each piece of second data and the second-level cluster center closest to the each piece of second data based on results of the calculating.
