GPTQ-2D：立方时间双边自适应舍入算法

AI 摘要

本文提出GPTQ-2D算法，用于在二次度量下将实数矩阵舍入为整数，处理左右两侧均有基矩阵的双边自适应舍入问题。该算法以立方时间产生与四时间方法相同的舍入矩阵，通过反对角线顺序并行舍入独立条目。

GPTQ-2D: Cubic-Time Two-Sided Adaptive Rounding Abstract Adaptive rounding methods such as GPTQ, or equivalently Babai's nearest plane algorithm, round a real matrix to integers under a quadratic metric. They process the entries in a fixed order, one at a time, propagating each rounding error to the entries not yet processed through a triangular feedback matrix. We study the two-sided version of this task, in which fixed nonsingular basis matrices act on both the left and the right of the residu
