WSLLN:Weakly Supervised Natural Language Localization Networks (D19-1)
Copied to clipboard
| Challenge: | Existing methods to learn correspondence between visual segments and texts require temporal coordinates for training, which leads to high costs of annotation. |
| Approach: | They propose weakly supervised language localization networks to detect events in untrimmed videos . they train with only video-sentence pairs without accessing to temporal locations of events . |
| Outcome: | Experiments on ActivityNet Captions and DiDeMo show that WSLLN performs state-of-the-art. |
DocQueryNet: Value Retrieval with Arbitrary Queries for Form-like Documents (2022.coling-1)
Copied to clipboard
| Challenge: | Existing methods that only address a fixed set of fields are difficult to use for different form types. |
| Approach: | They propose a value retrieval method with arbitrary queries for form-like documents . they propose 'docQueryNet' to predict target value based on understanding of layout and semantics of a form . |
| Outcome: | The proposed method outperforms existing methods on value retrieval . it improves document understanding on large-scale model pre-training by 17% . |
