MPTc-Bench: Measuring Cross-market Generative Ability of Vision-Language Models via Movie Poster Transcreation (2026.findings-acl)
Copied to clipboard
| Challenge: | Recent work adapts textual transcreation to image editing and formulates image transcreations to better match a target audience while preserving meaning. |
| Approach: | They propose a two-stage planner-editor pipeline in which an VLM planner specifies executable edits and an image editor renders them. |
| Outcome: | The proposed model can transcreate a visual asset for a different market while preserving its identity while matching market-specific design preferences and multilingual typography. |

Progressive LoRA for Multimodal Continual Instruction Tuning (2025.findings-acl)
Copied to clipboard
| Challenge: | Existing approaches to MCIT address Catastrophic Forgetting and Knowledge Transfer (KT) but using a fixed number of shared LoRA blocks across tasks can lead to knowledge interference. |
| Approach: | They propose a framework that uses a fixed number of shared LoRA blocks to reduce knowledge interference. |
| Outcome: | The proposed framework outperforms existing approaches on the latest MCIT benchmark. |
GHAN: Graph-Based Hierarchical Aggregation Network for Text-Video Retrieval (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches to text-video retrieval are limited due to structural and semantic differences between text and video. |
| Approach: | They propose an end-to-end graph-based hierarchical aggregation network for text-video retrieval according to the hierarchy possessed by text and video. |
| Outcome: | The proposed model achieves Recall@1 of 73.0%, 65.6%, and 64.0% better than the current state-of-the-art model. |
