Since the fuzzy C-means clustering algorithm is easy to fall into local extremum,fuzzy C-means clustering algo-rithm based on the improved quantum particle swarm optimization (QPSO) is proposed. The local search ability and quantum gates update strategy were improved by making full use of the advantages of fast convergence of QPSO. The experimental results show that the algorithm improves the search ability and clustering effect of fuzzy clustering algorithm,and has superiority in the aspects of global optimization capability,jumping out of local optimum capacity and convergence rate.
