# Model Checkpoints for Multilingual Machine-Generated Text Portion Detection

## Model Details

### Model Description
- Developed by: 1-800-SHARED-TASKS
- Funded by: Cohere's Research Compute Grant (July 2024)
- Model type: Transformer-based for multilingual text portion detection
- Languages (NLP): 23 languages (expanding to 102)
- License: Non-commercial; derivatives must remain non-commercial with proper attribution

### Model Sources

- **Paper:** [ACL Anthology Placeholder]
- **Presentation:** [Multi-lingual Machine-Generated Text Portion(s) Detection](https://static1.squarespace.com/static/659ac5de66fdf20e1d607f2e/t/66d977a49597da76b6c260a1/1725527974250/MMGTD-Cohere.pdf)

## Uses
The dataset is suitable for machine-generated text portion detection, token classification tasks, and other linguistic tasks. The methods applied here aim to improve the accuracy of detecting which portions of text are machine-generated, particularly in multilingual contexts. The dataset could be beneficial for research and development in areas like AI-generated text moderation, natural language processing, and understanding the integration of AI in content generation.

## Training Details
The model was trained on a dataset consisting of approximately 330k text samples from LLMs Command-R-Plus (100k) and Aya-23-35B (230k). The dataset includes 10k samples per language for each LLM, with a distribution of 10% fully human-written texts, 10% entirely machine-generated texts, and 80% mixed cases.

## Evaluation

### Testing Data, Factors & Metrics
The model was evaluated on a multilingual dataset covering 23 languages. Metrics include Accuracy, Precision, Recall, and F1 Score at the word level (character level for Japanese and Chinese).

### Results
Here are the word-level metrics for each language and ** character-level metrics for Japanese (JPN) and Chinese (ZHO):
