首先在对比实验的基础上得出推论 ,在训练矢量本身分布不均匀的情况下 ,初始码本的设置应该使由各初始码字聚类形成的胞腔在总畸变上尽可能均衡 .分析并给出了这一初始码字生成原则的合理解释 .以此原则出发 ,提出了一种新的初始码字生成算法 .最后用实验验证了这一原则和基于此原则的初始码字生成算法的有效性 .
First of all, based on the comparative experiments, we deduce that in the case of uneven distribution of the training vectors, the initial codebook should be set so as to make the cell cavity formed by clustering each initial code as balanced as possible on the total distortion. A new initial code generation algorithm is proposed based on this principle.Finally, this principle is verified by experiments and the algorithm of initial code generation based on this principle Effectiveness.
