About training the model

[chautuankien]

I found your paper on the internet and get interested with it. I want to ask about the way you trained the model.
I saw that you are using SWIN transformer in your model. When you trained the model, did you train it from scratch with your dataset, or did you use any pretrained weights? One more question, can you tell me what environments you used to train this model?
Thank you.
