A Simple and Effective Approach to Automatic Post-Editing with Transfer Learning (P19-1)
Copied to clipboard
| Challenge: | Existing APE systems generate artificial triplets of source sentences, machine translation outputs and human post-edits. |
| Approach: | They propose to use human post-edits to refine black-box machine translation (MT) models by fine-tuning pre-trained BERT models on both encoder and decoder of an APE system. |
| Outcome: | The proposed method improves on a dataset of 23K sentences on x86 GPUs. |
Adaptively Sparse Transformers (D19-1)
Copied to clipboard
| Challenge: | Recent architectures, notably the Transformer, learn powerful context-aware word representations through layered, multi-headed attention. |
| Approach: | They propose an adaptively sparse Transformer where attention heads have flexible, context-dependent sparsity patterns. |
| Outcome: | The proposed model improves interpretability and head diversity when compared to softmax-based models on machine translation datasets. |
