Reviews: Levenshtein Transformer

Detailed Comments "two atomic operations -- insertion and deletion" This is somewhat debatable. Under the LevT, an insertion operation first requires the number of slots to be predicted first, then the actual insertions are predicted. This is not completely atomic. Section 1. "(up to 5 speed-up" Figure 4. Section 4.1 "Analysis of Efficiency" This reviewer thinks the paper is quite misleading in the speed comparison, and iteration comparison. Figure 4 add/subtracts a U[0, 0.5) noise to the figure, which means it can subtract iterations -- this gives a misleading plot.
