The code seems to be running. However, the ELBO loss is identical through all the epochs. Therefore, it seems that something is wrong with the training part. When I run the code with the data given on the webpage, I get the same results as on the webpage (the training part works, ELBO loss is reduced through the epochs). I attach two m-files. ConvAE.m is the main code and Sinus.m is the sine wave data set. I have not attached the other helper functions as they are identical to the ones on the webpage. Some parameters in ConvAE.m have been adjusted to match the data set that I use.
Can anyone spot the problem?
