Additional context

First of all, thank you for the code. However, I found that the information entropy of each channel of the model output tensor was used when selecting the band in your code. In the original paper, “According to the learned sparse band weights, we can determine the informative bands by averaging the band weights for all the training samples. Those bands that have larger average weights are considered to be significant since they make more contributions to the reconstruction.”That means the weight of each channel output by the channel attention module is used ,this is different from the method you use，is there any reason for you to do this,please?
