This way, following the notation in Section 3.1, we set While we find that independently computing the similarity measure between all word pairs is prohibitively slow, the computation of the entire similarity matrix XW Z T can be easily vectorized using popular linear algebra libraries, obtaining big performance gains.
for that reason, we carried out some experiments in crosslingual word similarity as a way to test our method in a different task and allowing to compare it to systems that use richer bilingual data.
