Pre-training via Leveraging Assisting Languages for Neural Machine Translation (2020.acl-srw)
Copied to clipboard
| Challenge: | Sequence-to-sequence (S2S) pre-training with large monolingual data is not always available for the languages of interest (LOI). |
| Approach: | They propose to use monolingual corpora of other languages to complement the scarce monolingual LOI by script mapping (Chinese to Japanese) . Using only Chinese and French monolinguals, they improve Japanese-English translation quality by up to 8.5 BLEU in low-resource scenarios. |
| Outcome: | The proposed approach improves Japanese-English translation quality by up to 8.5 BLEU in low-resource scenarios. |
Grammar-based Decoding for Improved Compositional Generalization in Semantic Parsing (2023.findings-acl)
Copied to clipboard
| Challenge: | Sequence-to-sequence (seq2sequ) models have been successful in semantic parsing tasks but struggle on out-of-distribution data. |
| Approach: | They propose to use a large-scale dialogue dataset to evaluate compositional generalization of semantic parsing. |
| Outcome: | The proposed model outperforms BART- and T5-based models on the SMCalflow-CS dataset on the zero-shot learning task. |

| Challenge: | Sequence-to-sequence (seq2sequ) models are a ubiquitous tool for text generation but they are not suitable for many other tasks. |
| Approach: | They propose to use UE techniques to identify out-of-domain (OOD) inputs where the model is susceptible to errors. |
| Outcome: | The proposed methods outperform heavyweight ensembles on the task of OOD detection. |

| Challenge: | Sequence-to-sequence models fail to generalize in hierarchy-sensitive manner when performing syntactic transformations. |
| Approach: | They evaluate whether seq2seq models generalize hierarchically on two transformations . they use pre-trained models and their multilingual variants to test their generalization . |
| Outcome: | The proposed models generalize hierarchically on two transformations in English and German. |

| Challenge: | Sequence-to-sequence (SEQ2SEQ) models have been successfully applied to automatic math word problem solving. |
| Approach: | They propose an equation normalization method to normalize duplicated equations and propose an ensemble model to combine their advantages. |
| Outcome: | The proposed model outperforms the previous state-of-the-art models on the math word problem solving. |
Attend to Medical Ontologies: Content Selection for Clinical Abstractive Summarization (2020.acl-main)
Copied to clipboard
| Challenge: | Existing studies have reported that clinicians read the IMPRESSION as they have less time to review findings. |
| Approach: | They propose to augment salient ontological terms into the abstractive summarizer by augmenting salient ontologies into the semantic summariser. |
| Outcome: | The proposed model significantly improves state-of-the-art results in terms of ROUGE metrics on two publicly available clinical data sets. |
Structural generalization is hard for sequence-to-sequence models (2022.emnlp-main)
Copied to clipboard
| Challenge: | Sequence-to-sequence models have been successful across many NLP tasks, but they have low generalization accuracy . |
| Approach: | They propose to use linguistic knowledge to overcome generalization limitations of seq2seq models . they show that human beings are able to understand and produce linguistic structures they have never observed before . |
| Outcome: | The proposed models can overcome this limitation by having linguistic knowledge built in. |
Multi-pass Decoding for Grammatical Error Correction (2024.emnlp-main)
Copied to clipboard
| Challenge: | Seq2edit models decode only once without aware of subsequent tokens. |
| Approach: | They propose to iteratively refine the correction results of seq2seq models via Multi-Pass Decoding (MPD) to improve performance, but MPD increases inference costs . they propose to merge the source input and previous round correction result into one sequence. |
| Outcome: | Experiments on the CoNLL-14 and BEA-19 test set show that the proposed approach improves over baselines. |
Automatic Grammatical Error Correction for Sequence-to-sequence Text Generation: An Empirical Study (P19-1)
Copied to clipboard
| Challenge: | Sequence-to-sequence (seq2sequ) models have a weakness: they cannot always generate sentences without grammatical errors. |
| Approach: | They propose to use automatic grammatical error correction to improve seq2seq models . they conduct experiments on machine translation, formality style transfer, sentence compression and simplification . |
| Outcome: | The proposed system can improve grammaticality of generated text and improve formal style tasks. |
