How Much Gradient Does Truncated Backprop Lose in Looped Transformers?
arXiv:2610.28871v1 Announce Type: new Abstract: Looped transformers reuse one block of layers many times and are often trained by backpropagating through only the last k loops. We measure how much of the weight gradient this throws away, exactly and for every k from one backward pass, on nine loope…
