1.提出frequency enhanced decomposed Transformer结构,融合了seasonal-trend分解,来更好地捕捉时间序列的全局特性。 2.在Transformer结构中提出了傅里叶和小波enhanced blocks来捕捉ts中重要的结构,通过频域映射。它们作为self-attention和cross-attention的替代。 3.通过随机
是在autoformer的架构上继续改进序列分解和注意力的工作,且在六个数据集上的结果和autoformer相比都有明显的提升。 文章的主要改进是基于傅立叶变换和小波变换,频域分析,公式基本看懂,但没太多idea哈哈,本周打算看kdd的文章,和多做点实验,从试验结果中获得新的insight。 fedformer (Frequency Enhanced DecomposedTrans...
The authors of the paper "FEDformer: Frequency Enhanced Decomposed Transformer for Long-term Series Forecasting" have made an attempt to solve this problem. They compare the actual data of a time series with its predicted values obtained from the vanilla Transformer. Below is a screenshot from ...

Frequency Enhanced Decomposed Transformer (FEDformer) is more efficient than standard Transformer with a linear complexity to the sequence length. Our empirical studies with six benchmark datasets show that compared with state-of-the-art methods, FEDformer can reduce prediction error by 14.8% and 22....

Besides being more effective, the proposed method, termed as Frequency Enhanced Decomposed Transformer ({\bf FEDformer}), is more efficient than standard Transformer with a linear complexity to the sequence length. Our empirical studies with six benchmark datasets show that compared with state-of-...
