# InsureDocClassifier — Insurance Document Classification

**Created by [Bytical AI](https://bytical.ai)** — AI agents that run insurance operations.

## Model Description

InsureDocClassifier is a 12-class insurance document classifier built on ModernBERT-base. It automatically categorizes insurance documents into their correct type, enabling automated document routing, indexing, and processing in insurance operations.

### Document Classes (12)

| ID | Document Type | Description |
|----|--------------|-------------|
| 0 | Policy Schedule | Policy details and coverage summary |
| 1 | Certificate of Insurance | Proof of insurance document |
| 2 | Claim Form | Insurance claim submission form |
| 3 | Loss Adjuster Report | Assessment report from loss adjuster |
| 4 | Bordereaux — Premium | Premium transaction records |
| 5 | Bordereaux — Claims | Claims transaction records |
| 6 | Endorsement | Policy amendment document |
| 7 | Renewal Notice | Policy renewal notification |
| 8 | Statement of Fact | Declaration of material facts |
| 9 | FNOL Report | First Notification of Loss report |
| 10 | Subrogation Notice | Recovery rights notification |
| 11 | Policy Wording | Full policy terms and conditions |

### Training Details

| Parameter | Value |
|-----------|-------|
| Base Model | answerdotai/ModernBERT-base |
| Training Samples | 10,000 synthetic insurance documents |
| Epochs | 5 |
| Eval Loss | 4.17e-06 |
| GPU | NVIDIA Tesla T4 16GB |

### Evaluation Results

| Metric | Score |
|--------|-------|
| **Accuracy** | **1.0** |
| **F1 (macro)** | **1.0** |
| **F1 (weighted)** | **1.0** |
| Eval Samples/sec | 32.96 |

## How to Use

```python
from transformers import AutoModelForSequenceClassification, AutoTokenizer

model = AutoModelForSequenceClassification.from_pretrained("piyushptiwari/InsureDocClassifier")
tokenizer = AutoTokenizer.from_pretrained("piyushptiwari/InsureDocClassifier")

text = "We hereby confirm that the above-named insured holds a valid policy of insurance..."
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=512)
outputs = model(**inputs)
predicted_class = outputs.logits.argmax(-1).item()

labels = {
    0: "Policy Schedule", 1: "Certificate of Insurance", 2: "Claim Form",
    3: "Loss Adjuster Report", 4: "Bordereaux — Premium", 5: "Bordereaux — Claims",
    6: "Endorsement", 7: "Renewal Notice", 8: "Statement of Fact",
    9: "FNOL Report", 10: "Subrogation Notice", 11: "Policy Wording"
}
print(f"Document type: {labels[predicted_class]}")
```
