I tried to contact you via email(wbandar1@jhu.edu), but dont get reply, I really need your help, thank you.T T
@fyoung26 I am not exactly sure what is the reason for lower scores on the Botswana dataset. Let me look into it.
@wgcban Thank you sincerely, I'm looking for your reply💖
Hi @fyoung26 . May I ask, did you solve your puzzle?

Hi @maozan , I didn't solve it yet, do you have any idea about?
@fyoung26我不确定博茨瓦纳数据集得分较低的原因是什么。让我调查一下。
Hello Sir, Thank you for the code and work on HyperTransformer. I am very confused about the data set processed by matlab. Could you please send me a copy of the processed data set? Email: xiaozhengwang95@gmail.com. Thank you very much.

@HaiMaoShiTang Hi, I am not sure about I still have the dataset saved in my machine since I am not continuing right now, but I will check and respond to you tomorrow. Thanks.
Hello, thank you very much for your reply. It will help me a lot. Thank you very much.

Hi @wgcban , it looks like there are many issues with the code and also with the pretrained.
E.g. dataset padova:
I downloaded your pretrained of N_modules 8 for pavia and I tried to compute the PSNR, running the test function.
The test function returns a PSNR of 41.60820770263672 but in the paper you wrote 43.80!
How can I replicate your results? I'm doing something wrong? Could you please share the your datasets? Thanks a lot for your help!

Hello Sir, Thank you for the code and work on HyperTransformer. I'm also confused about the preprocessed data set. Could you please send me a copy of the processed data set? My Email: chenjiafu113@gmail.com. Thank you very much.
Hello Chaminda,
Thank you for the code and work on HyperTransformer. When I tried to reproduce the score on the botswana4 dataset, the metrics I got are far from expectation:
pretrain: {"loss": 0.07473030593246222, "cc": 0.9290400743484497, "sam": 3.0020320415496826, "rmse": 0.021659649908542633, "ergas": 0.6483104825019836, "psnr": 27.892120361328125}
train: {"loss": 0.08555552270263433, "cc": 0.8993576765060425, "sam": 3.35520076751709, "rmse": 0.02654602937400341, "ergas": 0.7366535663604736, "psnr": 26.585630416870117}
I also used the trained model you provided, and I got: {"loss": 0.05360260047018528, "cc": 0.9539724588394165, "sam": 2.2932522296905518, "rmse": 0.01636636257171631, "ergas": 1.8692368268966675, "psnr": 30.393962860107422}
Both results are far from expectation.
Then,I checked the github issue of HyperTransformer, then I changed "max_value": 8000 to "max_value": 9816(I got this value from the proccess code of matlab),the pretrain metrics got improvement:
{"loss": 0.03306201007217169, "cc": 0.964657187461853, "sam": 1.863145351409912, "rmse": 0.01357241254299879, "ergas": 0.3927982747554779, "psnr": 32.014068603515625}
But still far away from expectation.
Do you know how to solve this problem?
