Compositional Generalisation with Structured Reordering and Fertility Layers (2023.eacl-main)
Copied to clipboard
| Challenge: | Seq2seq models struggle with compositional generalisation, i.e. generalising to new and potentially more complex structures than seen during training. |
| Approach: | They propose a flexible end-to-end differentiable neural model that composes two structural operations: a fertility step and a reordering step. |
| Outcome: | The proposed model outperforms seq2seq models on compositional splits of realistic semantic parsing tasks. |
