Parameters can't be changed

[Taikakim]

I've tried changing the parameters in the parameters.json file in the model directory and running the training again. The missing features are now added, but training can't start and the model is rendered nonfunctional. Here's the output for example for a paranmeter file like this. It would be nice to have a short piece in the documentation about these parameters. I guess they should be extra controlled variables for the autoencoder, against which it can test it's function? The RNN, if turned on, created a functional model though, altough I've yet to see how the output differs from the usual:

I got this output (I cut out the gazillion training steps)
