# PII NER Azerbaijani

**PII NER Azerbaijani** is a fine-tuned Named Entity Recognition (NER) model based on XLM-RoBERTa. It is trained on Azerbaijani pii data for classification personally identifiable information such as names, dates of birth, cities, addresses, and phone numbers from text.

## Model Details

- **Base Model:** XLM-RoBERTa
- **Training Metrics:**
  - **Epoch 1:** Training Loss: 0.156, Validation Loss: 0.1309, Precision: 0.7794, Recall: 0.7940, F1: 0.7866, Accuracy: 0.9590  
  - **Epoch 2:** Training Loss: 0.1196, Validation Loss: 0.1172, Precision: 0.8042, Recall: 0.8078, F1: 0.8060, Accuracy: 0.9618  
  - **Epoch 3:** Training Loss: 0.1069, Validation Loss: 0.1129, Precision: 0.8096, Recall: 0.8213, F1: 0.8154, Accuracy: 0.9639

- **Test Metrics:**  
  - Loss: 0.11616, Precision: 0.80187, Recall: 0.80821, F1: 0.80503, Accuracy: 0.96264

## Usage

To use the model for spell correction:

```python
import torch
from transformers import AutoTokenizer, AutoModelForTokenClassification

model_id = "LocalDoc/private_ner_azerbaijani"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForTokenClassification.from_pretrained(model_id)

test_text = (
    "Salam, mənim adım Əli Hüseynovdur. Doğum tarixim 15.05.1990-dır. Bakı şəhərində, Nizami küçəsində, 25/31 ünvanında yaşayıram. Telefon nömrəm +994552345678-dir."
)

inputs = tokenizer(test_text, return_tensors="pt", return_offsets_mapping=True)

offset_mapping = inputs.pop("offset_mapping")

with torch.no_grad():
    outputs = model(**inputs)

predictions = torch.argmax(outputs.logits, dim=2)

tokens = tokenizer.convert_ids_to_tokens(inputs["input_ids"][0])
offset_mapping = offset_mapping[0].tolist()

    if word["label"] == "O":
        if current_entity is not None:
            entities.append(current_entity)

            else:
                entities.append(current_entity)
                current_entity = {
                    "type": word["label"],
                    "start": word["offsets"][0][0],
                    "end": word["offsets"][-1][1]
                }
