Unsupervised Cross-lingual Transfer of Word Embedding Spaces
Table 5: Performance (measured using Pearson correlation) of all the methods in cross-lingual semantic word similarity prediction on the benchmark data from Conneau et al. (2017). The best score in the supervised and unsupervised category is bold-faced, respectively. The languages include English (en), German (de), Spanish (es), Persian (fa) and Italian (it). ”-” means that the model failed to converge to reasonable local minimal during the training process.

We can see that the unsupervised methods, including ours, perform equally well as the supervised methods, which is highly encouraging.
