"straightforward" from simply looking at the equations, we maintain that the multi-layer extension is a significant However, note from Figure 5 (appendix) the pattern in which the layers are sequentially "added" by the We consider the direction of finding other optimizations for layer choice an important future work. From eqn 3, you are correct, it is possible for all layers to contribute differently. Intuitively, the most impactful layers are added first. The decoding for this layer notation is shown in Figure 5 (appendix). We will be sure to clarify these points in the final version.
