Reconstruction Loss issue

[vickycs50]

Hi Daniel,
I executed the given code. However, the reconstruction loss of AE is not decreasing after several iterations. Instead, it keeps increasing in some epochs. would you please explain this behaviour?

I share the same issue as you, and my test results are favorable. I suspect that the loss function is the sum of three individual losses, which could potentially prevent the total loss from decreasing.
