Table 8: Performance of P2T-Tran
['Direction', 'Category', 'Basic Units', 'Text Space Dev', 'Text Space Test']
In this subsection, we report results on P2T-Tran, and also compare it against T2T-Tran. Since the outputs of both P2T-Tran and T2T-Tran are in text space, we only report their performances in text space. For P2T-Tran, we also experiment two variants, namely, P2T-Tran-Syllable and P2T-Tran-Subword. On the test set, the performance difference between P2T-Tran-Syllable and P2T-Tran-Subword is very small and almost neglect-able, which is different from the results on P2P-Tran, where differences between P2P-Tran-Syllable and P2P-Tran-Subword is small but noticeable.
