Papers with hierarchical attention
“Laughing at you or with you”: The Role of Sarcasm in Shaping the Disagreement Space (2021.eacl-main)
Copied to clipboard
| Challenge: | Detecting arguments in online interactions is useful to understand how conflicts arise and get resolved. |
| Approach: | They propose to use a corpus annotated with argumentative moves and sarcasm to model sarcastic relationships using deep learning architectures. |
| Outcome: | The proposed setup improves the argumentative relation classification task using deep learning architectures. |
Data-to-text Generation with Entity Modeling (P19-1)
Copied to clipboard
| Challenge: | Recent approaches to data-to-text generation have shown great promise thanks to the use of large-scale datasets and the application of neural network architectures which are trained end-to end. |
| Approach: | They propose an entity-centric neural architecture for data-to-text generation which uses hierarchical attention to create entity-specific representations which are dynamically updated. |
| Outcome: | The proposed model outperforms baselines in automatic and human evaluation on the RotoWire benchmark and a five-times larger dataset on the baseball domain. |
Heterogeneous Graph Neural Networks for Keyphrase Generation (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches for keyphrase generation generate uncontrollable and inaccurate absent keyphrases. |
| Approach: | They propose a graph-based method that captures explicit knowledge from related references. |
| Outcome: | The proposed model improves on baseline keyphrase generation models on multiple benchmarks. |
Dual Attention Network for Cross-lingual Entity Alignment (2020.coling-main)
Copied to clipboard
| Challenge: | Experimental results on three real-world cross-lingual entity alignment datasets have shown the effectiveness of DAEA. |
| Approach: | They propose a dual attention network for cross-lingual entity alignment . they use relation-aware graph attention and hierarchical attention to solve this problem . |
| Outcome: | The proposed approach can be applied to three real-world cross-lingual entity alignment datasets. |
H-Transformer-1D: Fast One-Dimensional Hierarchical Attention for Sequences (2021.acl-long)
Copied to clipboard
| Challenge: | Existing hierarchical methods to compute attention are superior to sub-quadratic ones . a particular type of attention, called multi-head scaled dot-product attention, is one of the main components of the Transformer architecture . |
| Approach: | They propose a hierarchical method to compute attention in the Transformer architecture . they perform extensive experiments to show that it captures hierarchic structure in sequences . |
| Outcome: | The proposed method outperforms sub-quadratic models on the Long Range Arena benchmark by over +6 points on average. |
Selective Attention for Context-aware Neural Machine Translation (N19-1)
Copied to clipboard
| Challenge: | Recent work in context-aware NMT considers only a few previous sentences as context . current systems fail to achieve fluent, good quality translation for a full document . |
| Approach: | They propose a top-down approach to hierarchical attention for context-aware NMT which uses sparse attention to selectively focus on relevant sentences in the document context. |
| Outcome: | The proposed approach outperforms context-agnostic baselines and context-based baselines on English-German datasets. |
Multimodal Abstractive Summarization for How2 Videos (P19-1)
Copied to clipboard
| Challenge: | Abstractive summarization is a task of producing a shorter version of the content in the document while preserving its information. |
| Approach: | They propose a new evaluation metric that measures semantic adequacy rather than fluency of abstractive summarization tasks. |
| Outcome: | The proposed model integrates information from different sources into a coherent output. |
