Rnn back propagation

WebSep 3, 2024 · Understanding RNN memory through BPTT procedure. Backpropagation is similar to that of feed-forward (FF) networks simply because the unrolled architecture resembles a FF one. But there is an important difference and we explain this using the above computational graph for the unrolled recurrences t t and t-1 t − 1. Webadapted to past inputs. Backpropagation learning is described for feedforward networks, adapted to suit our (probabilistic) modeling needs, and extended to cover recurrent net-works.
