PARAMETER-EFFICIENT MULTIMODAL INSTRUCTION TUNING FOR ROMANIAN VISION-LANGUAGE MODELS
Unlocking Multilingual AI for Low-Resource Languages
This research addresses the critical gap in multimodal NLP resources for Romanian, demonstrating how parameter-efficient fine-tuning can significantly improve visual question answering and image captioning capabilities. By translating and extending the Flickr30k dataset, we enable robust VLM adaptation, enhancing both accuracy and linguistic fluency for under-represented languages.

Absolute Improvement in BERTScore F1 for Romanian VQA with Qwen2-VL-RoVQA
| Model | BERTScore F1 (%) | ROUGE-L F1 (%) | BLEU |
|---|---|---|---|
| Qwen2-VL (7B) | 74.10 | 30.22 | 29.12 |
| Qwen2-VL-RoVQA (7B) | 80.15 | 44.25 | 67.86 |
| LLaMA-3.2 (11B) | 64.64 | 10.51 | 18.51 |
| LLaMA-3.2-RoVQA (11B) | 75.80 | 32.82 | 77.11 |
The fine-tuned Qwen2-VL-RoVQA achieved the highest overall performance, demonstrating that even a modestly sized model with targeted multilingual pre-training significantly benefits from task-specific Romanian supervision. LLaMA-3.2-RoVQA also shows substantial gains, with its BLEU score quadrupling after adaptation.
Case Study: Enhancing Romanian Fluency with Instruction Tuning
Our grammatical error analysis revealed a notable reduction in Word Error Rate (WER) across models after fine-tuning. For Qwen2-VL-RoVQA, the WER decreased from 17.35% to 14.12%. Similarly, LLaMA-3.2-RoVQA saw its WER drop from 19.72% to 15.96%. This indicates that parameter-efficient instruction tuning not only improves semantic accuracy but also significantly enhances the linguistic form and fluency of generated Romanian text, addressing critical challenges in low-resource NLP.
This improvement suggests that targeted instruction tuning with high-quality, human-verified data effectively mitigates grammatical inconsistencies, such as missing definite articles or diacritic loss, which are common challenges in Romanian text generation.
These modules highlight the robust capabilities developed through our approach, offering significant improvements for enterprise applications requiring precise and grammatically correct multimodal AI in Romanian.
