# Gretel GLiNER: Fine-Tuned Models for PII/PHI Detection
This **Gretel GLiNER** model is a fine-tuned version of the GLiNER base model `knowledgator/gliner-bi-base-v1.0`, specifically trained for the detection of Personally Identifiable Information (PII) and Protected Health Information (PHI). 
Gretel GLiNER helps to provide privacy-compliant entity recognition across various industries and document types.
For more information about the base GLiNER model, including its architecture and general capabilities, please refer to the [GLiNER Model Card](https://huggingface.co/knowledgator/gliner-bi-base-v1.0).

The model was fine-tuned on the `gretelai/gretel-pii-masking-en-v1` dataset, which provides a rich and diverse collection of synthetic document snippets containing PII and PHI entities.

1. **Training:** Utilized the training split of the synthetic dataset.
2. **Validation:** Monitored performance using the validation set to adjust training parameters.
3. **Evaluation:** Assessed final performance on the test set using PII/PHI entity annotations as ground truth.

For detailed statistics on the dataset, including domain and entity type distributions, visit the [dataset documentation on Hugging Face](https://huggingface.co/datasets/gretelai/gretel-pii-masking-en-v1).

### Model Performance

All fine-tuned Gretel GLiNER models demonstrate substantial improvements over their base counterparts in accuracy, precision, recall, and F1 score:

| Model                                 | Accuracy | Precision | Recall | F1 Score |
|---------------------------------------|----------|-----------|--------|----------|
| gretelai/gretel-gliner-bi-small-v1.0   | 0.89     | 0.98      | 0.91   | 0.94     |
| gretelai/gretel-gliner-bi-base-v1.0    | 0.91     | 0.98      | 0.92   | 0.95     |
| gretelai/gretel-gliner-bi-large-v1.0   | 0.91     | 0.99      | 0.93   | 0.95     |


## Installation & Usage

Ensure you have Python installed. Then, install or update the `gliner` package:

```bash
pip install gliner -U
```

Load the fine-tuned Gretel GLiNER model using the GLiNER class and the from_pretrained method. Below is an example using the gretelai/gretel-gliner-bi-base-v1.0 model for PII/PHI detection:

```python
from gliner import GLiNER

# Load the fine-tuned GLiNER model
model = GLiNER.from_pretrained("gretelai/gretel-gliner-bi-base-v1.0")

# Sample text containing PII/PHI entities
text = """
