Abstract :
A technique for efficient vector quantization (VQ) design based on conjugate-gradient search methods is introduced. It is demonstrated experimentally that the new design algorithm performs better than the generalized Lloyd algorithm in many cases in terms of computation time and/or quality of the codebook it produces
