(Upper) Directed acyclic computation graph along temporal and spatial dimension. (Middle) Loopy computation graph after vectorization along the temporal dimension. The loop is introduced by the reset kernel and is ignored in the backward path of SLAYER. (Lower) Vectorized backward path, applying IFT to back-propagate the gradients through the loopy computation graph.
