Furthermore, while single-model forecasting (SF) schemes have demonstrated effectiveness, there has been limited exploration of the potential for coupling VMD and encoder-decoder framework in mid- and long-term daily streamflow forecasting. To address these issues and further enhance the capability of...

First, the encoder receives the compressed input data and implements them in the hidden layer. Then, the compressed input data from the previous stage are reconstructed using the decoder stage. As the last layer of the encoder stage does not return a sequence, a repeat vector is required to ...
The hidden states of the stacked layer are fed into the encoder input. Then, the encoder processes the input sequence and forms the cell state network to be used by the decoder to estimate the output sequence. The decoder uses the estimated previous sample (𝑠′𝑛−1s′n−1) to ...

The repeat vector layer repeats the context vector received from the encoder and feeds it to the decoder as an input. This is repeated for n steps, where n is the number of future steps that must be predicted [108]. Similarly, to maintain one-to-one relationships on input and output, ...
The input of the decoder consists of two parts—one from the hidden intermediate data features of the output of the encoder and the other from the original input vector. The value to be predicted is assigned to 0, so as to prevent the previous position and pay attention to the information...
Similar to the encoder, the decoder consists of ConvLSTM cells. The cell state and hidden state for the 𝑛𝑡ℎ nth cell is denoted as 𝐶𝑑(𝑛)𝑡Ctd(n) and 𝐻𝑑(𝑛)𝑡Htd(n), respectively. Initially, 𝐶𝑑𝑡=𝑁Ct=Nd = 𝐶𝑒𝑡=𝑁Ct=Ne and 𝐻𝑑𝑡=...
