MaPPER: Multimodal Prior-guided Parameter Efficient Tuning for Referring Expression Comprehension (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for Referring Expression Comprehension (REC) lack specific domain abilities for precise local visual perception and visual-language alignment. |
| Approach: | They propose a framework for Parameter-Efficient Transfer Learning to localize a visual region via natural language using a prior-guided prior. |
| Outcome: | The proposed framework achieves the best accuracy compared to the current methods with only 1.41% tunable backbone parameters. |

| Challenge: | Large language models (LLMs) use tokenization methods but often obscure internal character structures within tokens. |
| Approach: | They propose a method that improves models’ ability to capture character positions within tokens by training them on reverse character prediction tasks using the tokenizer’s vocabulary. |
| Outcome: | Experiments show that the proposed method improves position prediction accuracy in large language models, enabling more precise identification of target characters in original text. |
