Plausible May Not Be Faithful: Probing Object Hallucination in Vision-Language Pre-training (2023.eacl-main)
Copied to clipboard
| Challenge: | Large-scale vision-language pre-trained (VLP) models generate unfaithful or nonsensical texts given the source input, which is called hallucination. |
| Approach: | They propose a VLP loss-based model to mitigate object hallucination by decoupling VLP objectives and a token-level image-text alignment. |
| Outcome: | The proposed model reduces object hallucination by 17.4% on two benchmarks. |
Gazetteer-Enhanced Attentive Neural Networks for Named Entity Recognition (D19-1)
Copied to clipboard
| Challenge: | Named entity recognition (NER) is a fundamental NLP task. |
| Approach: | They propose a gazetteer-based attentive neural network which can enhance region-based NER . they first model the mention-context association and then an auxiliary gazetteers . |
| Outcome: | The proposed approach can achieve state-of-the-art on ACE2005 named entity recognition benchmark. |
