Our systematic study of parameter-efficient multimodal instruction tuning for Romanian reveals substantial improvements in visual question answering and image captioning, alongside significant reductions in grammatical errors. The core of our approach lies in constructing high-quality Romanian datasets and leveraging lightweight LoRA adapters.
Enterprise Process Flow: Romanian Dataset Construction
| 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.
