Auto-Sizing the Transformer Network: Improving Speed, Efficiency, and Performance for Low-Resource Machine Translation (D19-56)
Copied to clipboard
| Challenge: | Neural sequence-to-sequence models are sensitive to architecture and hyperparameter settings. |
| Approach: | They incorporate architecture search into a single training run through auto-sizing . they show that auto-size can improve BLEU scores by up to 3.9 points . |
| Outcome: | The proposed algorithm improves BLEU scores on low-resource language pairs while removing one-third of the parameters from the model. |

| Challenge: | Lower-resource corpora have systematic issues, including mislabeled or nonstandard/ambiguous language codes. |
| Approach: | They manually audit the quality of 205 language-specific corpora released with five major public datasets. |
| Outcome: | The results show that lower-resource corpora have systematic issues even for non-proficient speakers. |
Neural Machine Translation of Text from Non-Native Speakers (N19-1)

| Challenge: | Neural Machine Translation (NMT) systems are known to degrade when confronted with noisy data. |
| Approach: | They propose to augment training data with sentences containing artificially-introduced grammatical errors to make the system more robust to such errors. |
| Outcome: | The proposed approach recovers 1.0 BLEU out of 2.4 BLUE lost due to grammatical errors on a set of Spanish translations of the JFLEG grammar error correction corpus. |
Masked Language Model Scoring (2020.acl-main)
Copied to clipboard
| Challenge: | Pretrained masked language models require finetuning for most tasks. |
| Approach: | They evaluate pretrained masked language models out of the box via their pseudo-log-likelihood scores (PLLs) they attribute this success to PLL’s unsupervised expression of linguistic acceptability without a left-to-right bias, greatly improving on scores from GPT-2 . |
| Outcome: | The proposed model outperforms autoregressive language models in a variety of tasks. |
