Does Pretraining for Summarization Require Knowledge Transfer? (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Existing theories claim that pretraining models learn linguistic knowledge from the pretraining corpus, but scientific explanations for these benefits remain unknown. |
| Approach: | They propose to use random character n-grams to test models on real corpora to see if the small residual benefit of using real data could be accounted for by the structure of the pretraining task. |
| Outcome: | The proposed task performs on documents consisting of character n-grams, whereas pretrained models perform on real corpora with no residual benefit. |

To Point or Not to Point: Understanding How Abstractive Summarizers Paraphrase Text (2021.findings-acl)
Copied to clipboard
| Challenge: | Abstractive summarization models have seen great improvements in recent years, but there is limited understanding of the strategies different models employ and how they relate their understanding of language. |
| Approach: | They characterize how one popular abstractive model uses an explicit copy/generation switch to control its level of abstraction vs extraction . they find that abstractive summarization models lack the semantic understanding necessary to generate paraphrases that are both abstractive and faithful to the source document. |
| Outcome: | The proposed model uses syntactic boundaries to truncate sentences that are often copied verbatim. |
Phrase-level Self-Attention Networks for Universal Sentence Encoding (D18-1)
Copied to clipboard
| Challenge: | Phrase-level self-attention networks (PSAN) can capture context dependencies at the phrase level instead of the sentence level. |
| Approach: | They propose to perform self-attention across words inside a phrase to capture context dependencies at the phrase level and use the gated memory updating mechanism to refine each word’s representation hierarchically with longer-term context dependency captured in a larger phrase. |
| Outcome: | The proposed model can achieve state-of-the-art performance across a plethora of NLP tasks including binary and multi-class classification, natural language inference and sentence similarity. |
