mBART50 Fine-tuned for Sinhala Spell Correction

Model Details

• Developed by: Team Surgical Masks
• License: CC BY 4.0
• Model Type: mBART50
• Language: Sinhala (si)
• Fine-tuned from: facebook/mbart-large-50
• Dataset: Sinhala Spell Correction Dataset
• Project: LMSpell

Research

This model was developed as part of our research on spell correction using pre-trained language models for low-resource languages.

• Published Paper: LMSpell: Spell Correction with Pre-Trained Language Models
• Extended Preprint: arXiv

Limitations

• The model is specifically fine-tuned for Sinhala spell correction and may not generalize to other languages.
• Performance may vary for informal text, social media content, code-mixed text, and text containing uncommon or domain-specific vocabulary.
• The model may occasionally modify text that is already correctly spelled.
