Model Card for Sinhala-BERT Fine-Tuned MLM

This model is a fine-tuned version of Ransaka/sinhala-bert-medium-v2 on the Sinhala News Corpus dataset for Masked Language Modeling (MLM).

Model Details

Model Description

This Sinhala-BERT model was fine-tuned specifically for the Sinhala language to improve its capabilities in Masked Language Modeling. It leverages the architecture of BERT and was further optimized on the Sinhala News Corpus dataset, aiming to achieve better contextual language understanding for Sinhala text.

• Developed by: [Thilina Gunathilaka]
• Model type: Transformer-based Language Model (BERT)
• Language(s) (NLP): Sinhala (si)
• License: Apache-2.0
• Finetuned from model [optional]: Ransaka/sinhala-bert-medium-v2

Model Sources [optional]

• Repository: [Your Hugging Face Repository URL]
• Dataset: TestData-CrossLingualDocumentSimilarityMeasurement

Uses

Direct Use

This model can directly be used for:

• Masked Language Modeling (filling missing words or predicting masked tokens)
• Feature extraction for Sinhala text

Downstream Use [optional]

This model can be fine-tuned further for various downstream NLP tasks in Sinhala, such as:

• Text Classification
• Named Entity Recognition (NER)
• Sentiment Analysis

Out-of-Scope Use

• This model is specifically trained for Sinhala. Performance on other languages is likely poor.
• Not suitable for tasks unrelated to textual data.

Bias, Risks, and Limitations

Like any language model, this model may inherit biases from its training data. It's recommended to assess model predictions for biases before deployment in critical applications.

Recommendations

• Evaluate model biases before deployment.
• Ensure fair and transparent use of this model in sensitive contexts.
