Backpropagation Through Time - What is backpropagation through time chain rule?


In a Recurrent Neural Network (RNN), sequences are processed incrementally. During backpropagation, the gradients are directed backwards across these time steps, a process referred to as backpropagation through time. The gradient with respect to the hidden state and the gradient from the previous time step converge at the copy node, where they are combined.
