Long-Distance Dependencies Don’t Have to Be Long: Simplifying through Provably (Approximately) Optimal Permutations (P19-2)
Copied to clipboard
| Challenge: | Neural models at the sentence level often need to model the interaction between words . however, there is no guarantee that the standard ordering of words is computationally efficient or optimal . |
| Approach: | They propose to use a dependency parse as a proxy for inter-word dependencies in a sentence to simplify the sentence with combinatorial objectives imposed on the sentence-parse pair. |
| Outcome: | The proposed model improves classification accuracy and reduces classification error by 2.0% over the previous state of the art. |
Cross-Lingual Unsupervised Sentiment Classification with Multi-View Transfer Learning (2020.acl-main)
Copied to clipboard
| Challenge: | Recent neural network models have achieved impressive performance on sentiment classification in English and other languages. |
| Approach: | They propose an unsupervised sentiment classification model that leverages an uncontrolled machine translation system and a language discriminator to learn a shared representation. |
| Outcome: | The proposed model outperforms other models on five language pairs. |
