Balancing Training for Multilingual Neural Machine Translation
Table 4: Mean and variance of the average BLEU score for the Diverse group. The models trained with MultiDDS-S perform better and have less variance.
['[BOLD] Method', '[BOLD] M2O  [BOLD] Mean', '[BOLD] M2O  [BOLD] Var.', '[BOLD] O2M  [BOLD] Mean', '[BOLD] O2M  [BOLD] Var.']
MultiDDS -S also results in smaller variance in the final model performance. We run MultiDDS and MultiDDS-S with 4 different random seeds, and record the mean and variance of the average BLEU score.
