Vector Quantization这项技术广泛地用在信号处理以及数据压缩等领域。事实上,在 JPEG 和 MPEG-4 等多媒体压缩格式里都有 VQ 这一步。 Vector Quantization 这个名字听起来有些玄乎,其实它本身并没有这么高深。大家都知道,模拟信号是连续的值,而计算机只能处理离散的数字信号,在将模拟信号转换为数字信号的时候,我们可...

also referred to as a “code” and the table mapping codes to centroids and vice versa is often referred as a “code book”. The result of k-means, a set of centroids, can be used to quantize vectors. Quantization aims to find an encoding of vectors that reduces the expected distortion...

The encoder values are projected down before being projected back to high dimensional after quantization. You can set this with the codebook_dim hyperparameter. import torch from vector_quantize_pytorch import VectorQuantize vq = VectorQuantize( dim = 256, codebook_size = 256, codebook_dim = 16...
Improved method and apparatus for vector quantization (VQ) to build a codebook for the compression of data. The codebook or "tree" is initialized by establishing N initial nodes and creating the remainder of the codebook as a binary codebook. Children entries are split upon determination of vario...
