[SOLVED] Decay Rate of Neural Network

tek

Hey there,
quite simple question, for which I couldn't find an answer in any documentation or thread:

What is the decay rate of the learning rate if you activate the "decay" button on a neural network operator?

Thanks for the answer!

Hi,

I'm afraid you are right. There is no documentation on how the decay influences the learning rate.
I've just looked it up from the source code: In every learning iteration the learning rate is diveded by the number of learning iterations plus one. Thus it drops to 1/2, 1/3, 1/4, etc.. of the default learning rate.

Best,
Nils

Thanks a lot!
