| Challenge: | Existing metric for object hallucination, CHAIR, is limited to MS COCO objects and synonyms. |
| Approach: | They propose a new open-vocabulary metric, ALOHa, which leverages large language models to measure object hallucinations. |
| Outcome: | The proposed metric correctly identifies 13.6% more hallucinated objects than CHAIR on HAT and 30.8% more on nocaps. |
