English(EN) Is INT8 Portable? A Cross-Platform Measurement Study of Quantized Inference on Embedded and Automotive Accelerators

INT8 量化可移植性研究揭示硬件间的不一致性

一项新研究挑战了 INT8 量化在不同硬件平台之间可普遍用于人工智能推理的假设。研究人员发现,INT8 的加速效果在很大程度上取决于特定的 CPU 指令集,某些硬件甚至出现了性能下降而非加速。此外,INT8 的输出在不同平台之间并不一致,当量化比例不是硬件原生支持时,会导致准确性下降。研究得出结论,对于确定性和准确性至关重要的嵌入式和汽车应用而言,“一次量化,随处部署”的方法并不可靠。 AI

影响 挑战了在边缘设备上高效部署 AI 模型的假设,需要针对不同平台进行优化。

    INT8 可移植吗?嵌入式和汽车加速器上量化推理的跨平台测量研究

    arXiv:2609.16085v1 Announce Type: cross Abstract: Eight-bit integer (INT8) post-training quantization is the default recipe for edge deployment, under a widely held assumption: INT8 makes inference faster at a small, predictable accuracy cost, and a model quantized once can be ca…
