English(EN) Hardware-Friendly Token-Group Activation Quantization for Low-Bit Mamba Super-Resolution

新型量化方法将Mamba超分辨率速度提升2.23倍

研究人员开发了一种名为Token-Group量化的新型训练后量化(PTQ)框架,用于基于Mamba的超分辨率模型。该方法解决了Mamba模型中跨空间Token的激活范围变化所带来的挑战,而这种变化会使低比特量化变得复杂。该框架通过使用轻量级预测器从预扫描特征推断分组,来近似一个硬件不友好的分组预言机,将具有相似裁剪范围的Token分配到同一组。此外,还引入了一个保频细化目标,以在校准过程中保持高频结构,从而在NVIDIA Jetson Orin Nano上实现了比FP16更好的性能和2.23倍的速度提升。 AI

影响 这项研究可能导致在边缘设备上更有效地部署基于Mamba的模型,提高性能并降低计算成本。
