Curriculum Learning and Minibatch Bucketing in Neural Machine Translation
Tom Kocmi, Ondřej Bojar · 2017
We examine the effects of particular orderings of sentence pairs on the on-line training of neural machine translation (NMT).We focus on two types of such orderings: (1) ensuring that each minibatch contains sentences similar in some aspect and (2) gradual inclusion of some sentence types as the training progresses (so called "curriculum learning").In our English-to-Czech experiments, the internal homogeneity of minibatches has no effect on the training but some of our "curricula" achieve a small improvement over the baseline.
