Write a program to implement vector quantization on a gray-scale image using a "vector" that consists of a 4x4 block of pixels. Design your codebook using all the blocks in the image as training data, ...

Vector quantization (VQ), which treats a vector as a compression unit, gains increasing research interests for its potential to accelerate large language models (LLMs). Compared to conventional ...

Vector Post-Training Quantization (VPTQ) is a Post-Training Quantization (PTQ) method that leverages vector quantization to quantize LLMs at an extremely low bit-width (<2-bit). VPTQ can compress a ...

This paper presents an effective vector quantizer for very low bit rate speech coding. Based on vector quantization for line spectral frequency (LSF) parameters, it reduces the storage and searching ...
