Query: An Affinity Propagation Based method for Vector Quantization Codebook
  Design   In this paper, we firstly modify a parameter in affinity propagation (AP) to
improve its convergence ability, and then, we apply it to vector quantization
(VQ) codebook design problem. In order to improve the quality of the resulted
codebook, we combine the improved AP (IAP) with the conventional LBG algorithm
to generate an effective algorithm call IAP-LBG. According to the experimental
results, the proposed method not only enhances the convergence abilities but
also is capable of providing higher-quality codebooks than conventional LBG
method.
