English(EN) When Do Foundation Models Pay Off? A Break-Even Analysis of Pretrained Time Series Forecasters

时间序列预测的基础模型:盈亏平衡分析揭示何时能带来回报

一项对时间序列预测基础模型的新分析表明,部署它们并非总是合理的。该研究将 Chronos、Moirai 和 Lag-Llama 等模型与 XGBoost 等传统方法在 30 个基准数据集上进行了比较。虽然基础模型在 15 个数据集上无条件地优于经典方法,但在其他数据集上,经典方法仅使用 2% 的训练数据就表现更优。研究还发现,LoRA 微调有时会降低在较短时间序列上的性能。 AI

影响 为从业者提供了一个框架,以决定是否投资于时间序列预测的基础模型,从而可能节省大量的计算资源。
