English(EN) WaterKron and FlipFlop Hessian: Information-Theoretically Grounded Quantization with Kronecker-factored Hessians

新的WaterKron方法利用克罗内克因子化的Hessian改进AI模型量化

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了WaterKron，一种利用克罗内克因子化Hessian近似进行训练后量化的新方法。该方法结合了双面GPTQ、水填充尺度和熵编码，引入了一个因子$\Phi$来量化克罗内克近似的失真惩罚。最小化该因子会导致FlipFlop Hessian，这得到了率失真理论的证明，并且在经验上显示与其他的Hessian近似方法相比，可以改善KL散度和困惑度。 AI

影响 这项研究通过改进量化技术，可能导致更高效的AI模型，从而降低计算成本和内存需求。
