When training a feedforward backpropagation network calc errors/train order....

Recommended Posts

Hi, I've developed a feedforward backpropagation network, where I calculate the errors for that layer, and then train the weights connected to that layer, and this works fine. But I was wondering, if it would be better to calculate the errors for all layers, and then train all the weights after that has been done? Thanks.

hi. well, there are a lot of back prop algorithms on the web. just keep searching.
in my opinion there is no difference between the two variants. but i'm not an expert in nn optimization, so keep searching.
