UniCM: A Unified Consistency Model For Efficient Multimodal Generation and Understanding (2026.findings-acl)
Copied to clipboard
| Challenge: | Consistency models (CMs) have shown promise in the efficient generation of both image and text. |
| Approach: | They propose to use a discrete token for both image and text generation to achieve a unified denoising perspective. |
| Outcome: | The proposed model outperforms SD3 on GenEval and Image Reward while being 1.5 faster at long-sequence generating speed. |
Incorporating Task-Specific Concept Knowledge into Script Learning (2023.eacl-main)
Copied to clipboard
| Challenge: | Existing work on Goal-Oriented Scripts ignore usage context and personal preferences . proposed tasks are restrictive and rely on overly simplified assumptions . |
| Approach: | They propose a novel approach to Goal-Oriented Script Completion that uses concept prompting and script-oriented contrastive learning to improve performance. |
| Outcome: | The proposed approach improves on a WikiHow-based dataset. |
