This model is very difficult to train. What training skills are there？

Thanks a lot for releasing the code of Meta-rPPG paper! We use the Deap dataset train Meta-rPPG model, but the model is difficult to converge. Do you have any training skills? Thaks a lot!

Hello, How do you process the DEAP dataset?

Hi,

A simple guideline is to pay attention to the partitioning of meta-training set into query and support sets. The rest of the training is straightforward and can be directly derived using our released code. Good luck!

Hello, How do you process the DEAP dataset?

I use PFLD to extract facial key points, and use the key points to generate facial ROI and mask. Then I downsampling the image and plethysmograph signal to 30fps. However, members of our group found that DEAPS dataset is difficult to converge. I recommend that you use UBFC dataset. Its video data and PPG signal are better, so you can use them directly without preprocessing.

I use the data example “exampl.pth” provided by you to train 30 iterations with default parameters. The loss is as follows. It seems that there is no convergence. I drew the prediction label and the real label, and found that the network didn't seem to be trained. Is it because there are too few samples?
