This methodology employs a vector quantization based on statistic measures to check whether is necessary create a new {\\it codebook}, then the nearest {\\it codebook} to the current input sample is found. After that, {\\it codebooks} are used to obtain the signal prediction at every ...
Transformed codebooks are obtained by a transformation of a given codebook to best match the statistical environment at hand. The procedure, though suboptimal, has recently been suggested for feedback of channel state information (CSI) in multiple antenn
QINCo is a neurally-augmented algorithm for multi-codebook vector quantization, specifically residual quantization (RQ). Instead of using a fixed codebook per quantization step, QINCo uses a neural network to predict a codebook for the next quantization step, conditioned upon the quantized vector so...

Also known as a vector field, this technique involves assigning a unique vector to each point in a 2D or 3D space describing the direction and magnitude of varying forces. Flow fi...
Interpolative Vector Quantization for Image Restoration described by [Sheppard97], over the [Gersho90] paper that it builds upon, is the substitution of the first VQ stage (2508,2608) with a block waveform coder comprising a Discrete Cosine Transform 2904 and transform coefficient Quantization stage...
