光伏预测

感谢作者提供的代码。
我是一名时间序列预测的初学者,之前学习过我师兄的论文(VMD对时序分解然后使用混合神经网络(CNN提取天气特征+GRU预测光伏分量,整合后再用CNN预测得到预测值)),现在先沿着这方面做下去,很庆幸能够看到作者的程序!!!不过有两个问题想请教一下,嘿嘿。
1、看了很多文献,暂时还未看到对CEEMDAN分解够使用聚类方法进行聚类,所以还是有点疑惑,这种方法除了减少计算步骤,还有什么优势嘛?

图1:CMMDAN分解后的图,会不会包含一点点模态重叠。
image
图2:对CMMDAN分解后在进行聚类,因为我看聚类标签并不是按顺序来的,所以可能存在imf1与imf4存在的情况,这种会对预测精度造成影响吗?
2、利用VMD对高频分量进行分解有什么优势嘛?

图3:VMD对高频分量分解图。
附加一个:之前了解过的分解方法,都是对分量预测进行求和的,这种将结果和相关因素矩阵再输入到神经网络中是不是就是作者在最后一步的迭代求预测结果。
因为我刚学不是很久,不知道会不会问一些很白痴的问题,还请作者不要介意,感谢作者的代码,如有相关的文献也可以推荐一下,万分期待作者百忙之中予以回复。谢谢!!!

lookahead?

I could be mistaken, but I think you might be incorporating some lookahead since the CEEMDAN decomposition views the entire series.
