Researchers have developed DASH-Q, a novel post-training quantization (PTQ) framework designed to reduce the memory footprint of large language models (LLMs) without requiring retraining. This method specifically addresses the degradation issues seen in ultra low-bit quantization by using a stable diagonal Hessian approximation and iterative weighted least squares. DASH-Q effectively filters out noise from limited calibration data, outperforming existing PTQ baselines by an average of 7.01% in zero-shot accuracy across five LLM models, even with very small calibration sets.
