Referring by name

[kadarakos]

I believe it would be a good idea to make it possible to refer by name to:

• Network parameters: for regularization or just analysis
• Return values: RNNs return "hidden states", "r states", "z states" and who knows what in the future

This would make experimentation easier. Functions like "last" or anything that has to do with prediction could query for "hidden states", functions related to regularizers could query for "weights" or for "activation vectors" and so on. I think this is would be nicer than say I want regularize(params[10]) or last(output[0]).

Not sure I understand what exactly you're suggesting. Could you give an example of how this would work?
