벡터 양자화(VQ)의 초기 코드북의 간단하고 성공적인 설계가 제시됩니다. 랜덤 방법과 같은 기존의 초기 코드북 알고리즘의 경우, 초기 코드북은 초기 코드워드의 선택에 크게 영향을 받고 훈련 벡터의 특징과 일치하기 어렵습니다. 제안된 방법에서는 훈련 벡터의 놈(Norm)에 따라 훈련 벡터를 정렬한다. 그런 다음 순서가 지정된 벡터는 다음과 같이 분할됩니다. N 그룹 N 코드북의 크기입니다. 초기 코드워드는 각 그룹의 중심을 계산하여 얻습니다. 이 초기화 방법은 강력한 성능을 가지며 VQ 알고리즘과 결합하여 코드북의 품질을 더욱 향상시킬 수 있습니다.

Abstract: A simple and successful design of initial codebook of vector quantization (VQ) is presented. For existing initial codebook algorithms, such as random method, the initial codebook is strongly influenced by selection of initial codewords and difficult to match with the features of the training vectors. In the proposed method, training vectors are sorted according to the norm of training vectors. Then, the ordered vectors are partitioned into N groups where N is the size of codebook. The initial codewords are obtained from calculating the centroid of each group. This initializtion method has a robust performance and can be combined with the VQ algorithm to further improve the quality of codebook.
