(i) Not all individual embedding sets are beneficial in this task; e.g., HLBL embeddings make FLORS perform worse in 11 out of 12 cases.
(ii) in most cases, embeddings improve system performance, which is consistent with prior work on using embeddings for this type of task (Xiao and Guo, 2013;Yang and Eisenstein, 2014;Tsuboi, 2014).
