Fulfulde Tokenizer for NLP tasks

Model Description

This tokenizer was developed for Fulfulde, a language from the fula[ni] family of languages in Cameroon. The tokenizer is based on the WordPiece model architecture and has been fine-tuned to handle the unique phonetic and diacritical features of the Fulfulde language.

• Developed by: DS4H-ICTU Research Group in Cooperation with the
• Language(s): Fulfulde Adamaoua (Fula[ni] language from Cameroon)
• License: Apache 2.0 (or specify if different)
• Model Type: Tokenizer (WordPiece)

• Paper: [Link to related paper if available]
• Demo: [Optional: link to demo]

Uses

• Direct Use: This tokenizer is designed for NLP tasks such as Named Entity Recognition (NER), translation, and text generation in the Fulfulde Adamaoua language.
• Downstream Use: Can be used as a foundation for models processing Fulfulde Adamaoua text.

Bias, Risks, and Limitations

• Biases: The tokenizer might not perfectly capture linguistic nuances due to the limited size of the Fulfulde corpus.
• Out-of-Scope Use: The tokenizer may not perform well for non-Fulfulde languages.

Training Details

• Training Data: Extracted from YambeFulfulde Adamaoua Bible text corpus (final_dataset.xlsx).
• Training Procedure: Preprocessing of text involved normalization of diacritics, tokenization using WordPiece, and post-processing to handle special tokens.
• Training Hyperparameters:
  • Vocabulary Size: 25,000
  • Special Tokens: [UNK], [PAD], [CLS], [SEP], [MASK]

Evaluation

• OOV Rate: 0.00%
• Tokenization Efficiency: Average tokens per sentence: 26.884630350194552
• Special Character Handling: Successfully handles diacritics and tone markers in Fulfulde Adamaoua.

Environmental Impact

• Hardware Type: Google Colab GPU
• Hours Used: 4 hours (training time)
• Cloud Provider: Google Cloud
• Carbon Emitted: Estimated using Lacoste et al. (2019) calculator
