Translating non Code-Switched Sentences. Our method preserves its strength on translating non code-switched sentences. In addition, on some test sets, our method is slightly better than the baseline when translating non code-switched source sentences. This can be explained from two aspects: First, the augmented data make the model more robust to perturbed inputs; Second, the pointer network makes the model better by copying certain source-side words Gulcehre et al.
