In the vanilla model, as shown in Figure 6(a), only the similar monolingual embeddings are clustered, such as the English words "died" and "killed", and the Chinese words "zhuxi" (president) and "zongtong" (presi-dent).
in the proposed method, no matter whether the similar source and target words are paired or not, they tend to cluster together; as shown in Figure 6(b) and 6(c).
