Large Language Models are In-context Teachers for Knowledge Reasoning (2024.findings-emnlp)
Copied to clipboard
| Challenge: | In-context teaching is a method of providing in-concept example rationales to a student to reason over unseen cases. |
| Approach: | They propose to use an LLM's self-elicited explanations as in-context demonstrations to prompt a student to reason over unseen cases. |
| Outcome: | The proposed model outperforms human-crafted demonstrations on medical question answering and human-created models outperfect human-made demonstrations. |
A Graph Interaction Framework on Relevance for Multimodal Named Entity Recognition with Multiple Images (2025.coling-main)
Copied to clipboard
| Challenge: | Existing methods to determine whether images are related to named entities are not effective in multi-image scenarios. |
| Approach: | They propose a graph interaction framework on relevance for Multimodal Named Entity Recognition with multiple images to integrate human abilities into the model. |
| Outcome: | The proposed framework achieves state-of-the-art on benchmark datasets and compares with CLIP and CLIP-based approaches. |
Jailbreaking Prompt Attack: A Controllable Adversarial Attack against Diffusion Models (2025.findings-naacl)
Copied to clipboard
| Challenge: | Text-to-image (T2I) models can be used to generate harmful content such as sexually explicit, unfaithful, and misleading or Not-Safe-for-Work (NSFW) images. |
| Approach: | They propose a more practical and universal attack that does not require the presence of a target model. |
| Outcome: | The proposed attack bypasses both text and image safety checkers while preserving high semantic alignment with the target prompt. |

| Challenge: | Low-resource tasks such as semi-supervised sequence generation require expert knowledge and cost. |
| Approach: | They propose a method for semi-supervised sequence generation where few examples are too scarce to fine tune a model. |
| Outcome: | The proposed method can generalize better than its teacher to unseen examples on semi-supervised sequence generation tasks. |
