Hyperdimensional Computing for Sustainable Manufacturing: An Initial Assessment
- 用高维计算替代传统AI模型做加工质量预测
- 训练能耗降200倍，推理能耗降175至1000倍
- 适合追求低功耗、高速推理的智能制造场景
智能制造可显著提升效率并降低能耗，但人工智能模型本身的能源需求可能抵消这些优势。本研究基于在位传感数据预测智能加工中的几何质量，对比了常见AI模型的能量消耗、准确率和速度。提出将高维计算（HDC）作为替代方案，在保持与传统模型相当准确率的同时，大幅降低能耗：训练阶段降低200倍，推理阶段降低175至1000倍。此外，HDC还将训练时间缩短200倍，推理时间缩短300至600倍，展现出在节能型智能制造中的巨大潜力。
原文摘要 · Abstract (English)
Smart manufacturing can significantly improve efficiency and reduce energy consumption, yet the energy demands of AI models may offset these gains. This study utilizes in-situ sensing-based prediction of geometric quality in smart machining to compare the energy consumption, accuracy, and speed of common AI models. HyperDimensional Computing (HDC) is introduced as an alternative, achieving accuracy comparable to conventional models while drastically reducing energy consumption, 200$\times$ for training and 175 to 1000$\times$ for inference. Furthermore, HDC reduces training times by 200$\times$ and inference times by 300 to 600$\times$, showcasing its potential for energy-efficient smart manufacturing.
