JParaCrawl: A Large Scale Web-Based English-Japanese Parallel Corpus
Table 6: Time required (hrs) to train NMT model for English-to-Japanese
['[BOLD] Data', '[BOLD] Model', '[BOLD] Without pre-training', '[BOLD] Fine-tuning']
For the fine-tuning experiments, we did not include the time for pre-training the model with JParaCrawl. Our fine-tuning approach drastically reduced the training time compared to training from the initial state. These results showed a domain-specific NMT model can be trained in a few hours starting from the pre-trained models with a parallel corpus of the domain.
