给出了一种易于实现的矢量量化随机松弛算法。它概括了通常的劳埃德迭代码本设计的扰动计算熵与独立的多维噪声，其方差随着算法的进展而减小。往往会有很大的改善。
An easily implementable stochastic relaxation algorithm for vector quantisation design is given. It generalises the usual Lloyd iteration in codebook design by perturbing the computed entroids with independent multidimensional noise, whose variance diminishes as the algorithm progresses. A significant improvement is often achieved.
