Few-Shot Natural Language Generation by Rewriting Templates
Table 8: Changing the size of the context. k represents the number of previous utterances used.
['[BOLD] k', '[BOLD] Naive  [BOLD] BLEU', '[BOLD] Naive  [BOLD] SER', '[BOLD] T2G2  [BOLD] BLEU', '[BOLD] T2G2  [BOLD] SER']
In these experiments, we concatenate the last k utterances to the system action representation obtained from the Naive and template based methods. Both models, Naive and T2G2, benefit from the additional context, showing an improvement of 3-4 BLEU points.
