| Challenge: | a limited human translation budget is required to train neural machine translation models. |
| Approach: | They propose to integrate active learning into neural machine translation techniques . they propose a word frequency based acquisition function and an uncertainty based method . |
| Outcome: | The proposed method outperforms other acquisition functions on a limited human translation budget. |
Memory-Efficient Differentiable Transformer Architecture Search (2021.findings-acl)

| Challenge: | Current neural architecture search methods suffer from huge computational cost. |
| Approach: | They propose a reversible recursive backpropagation algorithm that uses the last layer to store the outputs of the network. |
| Outcome: | The proposed algorithm outperforms standard Transformers on three sequence-to-sequence datasets. |
Multi-split Reversible Transformers Can Enhance Neural Machine Translation (2021.eacl-main)
Copied to clipboard
| Challenge: | Large-scale transformers have been shown to improve neural machine translation performance but training these wider and deeper networks could be extremely memory intensive. |
| Approach: | They propose a multi-split based reversible transformer and a backpropagation algorithm that does not need to store activations for most layers. |
| Outcome: | The proposed model outperforms the vanilla transformer by at least 1.4 BLEU points in three datasets. |
