Dynamic Emotion and Personality Profiling for Multimodal Deception Detection (2026.acl-long)
Copied to clipboard
| Challenge: | Existing methods for deception detection lack sample-level dynamic annotations for emotions and personality. |
| Approach: | They propose a multi-model multi-prompt annotation scheme and a strict label quality evaluation standard for deception, emotion, and personality annotations. |
| Outcome: | The proposed framework outperforms state-of-the-art models on the MDPE and DDEP datasets. |
Learning Diverse Responses with Prefix-Conditioned Supervised Fine-Tuning (2026.acl-long)
Copied to clipboard
| Challenge: | Large language models exhibit highly homogeneous, repetitive responses, resulting in inefficient exploration. |
| Approach: | They propose a method that constructs semantically consistent yet distributionally distinct prior contents to different responses and decouple the one-to-many mapping. |
| Outcome: | The proposed method improves absolute performance by 5.3% and increases generation diversity by 198.3% on average while significantly enhancing output diversity and test-time scaling. |
