| Approach: | They propose a multi-modal few-shot relation extraction model that leverages both textual and visual semantic information to learn a multiple-modal representation jointly. |
| Outcome: | The proposed model leverages both textual and visual semantic information to learn a multi-modal representation jointly. |
