1997年9月，NIST征集AES方案，以替代DES。 1999年8月，以下5个方案成为最终候选方案：MARS, RC6, Rijndael, Serpent, Twofish。 2000年10月，由比利时的Joan Daemen和Vincent Rijmen提出的算法最终胜出。（ Rijndael 读成Rain Doll。） http://www.esat.kuleuven.ac.be/~rijmen/rijndael/-September 1997, NIST AES assembly program to replace DES. In August 1999, the following five programs become final candidate : MARS, RC6, Rijndael, Serpent, Twofish. In October 2000, from Belgium J.J.K.Daemen3 Joan and Vincent Rijmen proposed algorithm eventually win. (Rijndael read Rain Doll.) Http://www.esat.kuleuven.ac.be/ ~ rijmen/rijndael /

提出了一种用于矢量量化的改进的聚类算法,该算法在MKM(Modified K-Means)算法的框架的基础上,对初始码本的生成、失真测度的选择、非典型胞腔的处理等方面进行了改进,从而减少了原算法在能量和增益上对聚类结果的影响.并将该算法应用于波形编辑孤立字识别器,这种识别器直接对语音样本的时域波形进行训练和聚类,不需要提取语音参数,算法复杂度较低,加上提出的聚类算法失真测度简单易实现,对芯片的运算能力要求不高,非常适用于有低成本要求的语音识别器场合.通过中文元音字识别的实验证明,在相同码本尺寸下,运用改进后的聚类算法的识别器的识别率有所提高.
