Table 1: Best results for each model. BLEU score, seconds per epoch and number of epochs it took to converge to the best BLEU score.
['Model', 'BLEU', 'Sec/epoch', 'Epochs to converge', 'Num. of parameters']
Note that while CNN achieves a similar BLEU score to Transformer, it does so much slower, taking over 50 epochs. Transformer is the clear winner, while taking not much longer to run than other models.
