Hi Guys, recently i saw a post on the forum related LSTM auto encoder, and want to play with it to have some fun. I tried a few different architectures ( lstm, covn1d, conv2d ) to model timeseries and image restoration. I found two common problems discussed on this forum, also other place such as stack overflow, but never seem to be sorted out.
-
restored data is simply an average of the original input - a problem with my lstm and conv1d based AE;
-
loss not decreasing - however, for a covn2d image autoencoder, it does reproduce an image similar to original.
just wondering if your guys noticed that same, and what is your solution ?
thanks
