New zero-shot quantization method transfers robustness via weight-space arithmetic

Researchers have developed a novel method called zero-shot quantization, which leverages weight-space arithmetic to improve model robustness to quantization. This technique extracts a "quantization vector" from a donor task and applies it to a receiver model, enhancing post-training quantization accuracy by up to 60% in a 3-bit setting without requiring quantization-aware training. The method has demonstrated substantial gains across various vision and language models and over 30 tasks, suggesting that quantization robustness can be isolated and transferred through algebraic manipulation of model weights. AI

IMPACT This method could enable more efficient deployment of large models on resource-constrained devices by reducing model size without significant accuracy loss.

    Zero-Shot Quantization via Weight-Space Arithmetic

    arXiv:2604.03420v4 Announce Type: replace-cross Abstract: We show that robustness to post-training quantization (PTQ) is a transferable direction in weight space. We call this direction the quantization vector: extracted from a donor task by simple weight-space arithmetic, it can…
