Our basic flow is a training loop: each time we pass through the loop (called an "epoch"), we compute a forward pass on the network and implement backpropagation to adjust the weights. The Universal Transformer repeatedly refines a series of vector representations (shown as h 1 to h m) for each position of the sequence in parallel, by combining information from different positions using self-attention and applying a recurrent transition function. The original papers on seq2seq are Sutskever et al. and assume we will always have just 1 dimension on the second axis. User Surveys. For example, sliding over 3, 4 or 5 words at a time.
