Researchers have published a paper detailing advancements in quantized matrix multiplication, specifically for large language models (LLMs). This second part of their work focuses on scenarios where the covariance matrix of the input data is known, which is common in weight-only post-training quantization of LLMs. The study shows how a 'waterfilling' approach, inspired by information theory, can improve quantization algorithms like GPTQ by allocating quantization rates more effectively across different dimensions, potentially nearing theoretical distortion limits.
