Unsupervised Pretraining for Neural Machine Translation Using Elastic Weight Consolidation

no code implementations • ACL 2019 • Du{\v{s}}an Vari{\v{s}}, Ond{\v{r}}ej Bojar

In our method, we initialize the weights of the encoder and decoder with two language models that are trained with monolingual data and then fine-tune the model on parallel data using Elastic Weight Consolidation (EWC) to avoid forgetting of the original language modeling task.
