F1 values of WHU-CD and DSIFN-CD

[yuwanting828]

Hello, I am trying to reproduce your model code, and it looks incorrect when using WHU-CD dataset as well as DSIFN-CD dataset, and the result appears too high than your result. But it looks normal when using LEVID-CD dataset. Do I need to change the pre-training?

[YangFanghan]

Can you share with me the training hyperparameters on the dsifn dataset, my training results are very different from the original text, and there is no best model after 60 epoch, this is my email, can you share the dsifn data collection, and your training methods and results。

[yuwanting828]

Hello,can you share me with your training results? and my dsifn dataset is downloaded from https://github.com/wgcban/ChangeFormer.You can read a lot from that, I hope my advice is useful to you

This is the result of my DSIFN dataset using two 2080 trained DSIFN datasets

2536110410@qq.com,This is my email,Do you facilitate the e-mail to communicate some details?

[yuwanting828]

I'm actually not sure about the specifics, I'm also a beginner, but my image_size is 256 , as well as the dataset partitioning, I used the dataset partitioned in the link I sent you.

I have encountered similar problems。The test result of level_cd data set is much higher than that of the paper. Can you share the super parameters with me? Thank you

请问您的数据集里的图片有无在训练前像论文里那样裁剪成256256，还是直接用作者的代码缩放图片成256256

[shizizuoing]

训练前像论文里那样裁剪成256_256，还是直接用作者的代码缩放图片成256_256

我是裁剪成256——256的，不是直接缩放。您的level-cd和原论文结果一样吗，我那个指标也很高

我没有裁剪，直接用的原数据集的1024*1024，那三个指标比论文里还低点。我现在才得到裁剪后的256-256数据集，现在准备试一下
