# Intentity AIBA - Multi-Task Banking Model 🏦🤖

## Model Description

**Intentity AIBA** is a state-of-the-art multi-task model that simultaneously performs:
1. 🌐 **Language Detection** - Identifies the language of input text
2. 🎯 **Intent Classification** - Determines user's intent
3. 📋 **Named Entity Recognition** - Extracts key entities from banking transactions

Built on `google-bert/bert-base-multilingual-cased` with a shared encoder and three specialized output heads, this model provides comprehensive understanding of banking and financial transaction texts in multiple languages.

## 🎯 Capabilities

### Language Detection
Supports 5 languages:
- `en`
- `mixed`
- `ru`
- `uz_cyrl`
- `uz_latn`

### Intent Classification
Recognizes 4 intent types:
- `create_transaction`
- `help`
- `list_transaction`
- `unknown`

### Named Entity Recognition
Extracts 6 entity types:
- `amount`
- `currency`
- `description`
- `receiver_hr`
- `receiver_inn`
- `receiver_name`

## 📊 Model Performance

| Task | Metric | Score |
|------|--------|-------|
| **NER** | F1 Score | 0.9891 |
| **NER** | Precision | 0.9891 |
| **Intent** | F1 Score | 0.9999 |
| **Intent** | Accuracy | 0.9999 |
| **Language** | Accuracy | 0.9648 |
| **Overall** | Average F1 | 0.9945 |

## 🚀 Quick Start

### Installation

```bash
pip install transformers torch
```

### Basic Usage

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

# Load model and tokenizer
model_name = "primel/intentity-aiba"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModel.from_pretrained(model_name)

# Note: This is a custom multi-task model
# Use the inference code below for predictions
```

### Complete Inference Code

```python
import torch
from transformers import AutoTokenizer, AutoModel
import json

class IntentityAIBA:
    def __init__(self, model_name="primel/intentity-aiba"):
        self.tokenizer = AutoTokenizer.from_pretrained(model_name)
        self.model = AutoModel.from_pretrained(model_name)

        # Load label mappings from model config
        self.id2tag = self.model.config.id2label if hasattr(self.model.config, 'id2label') else {}
        # Note: Intent and language mappings should be loaded from model files

        self.device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
        self.model.to(self.device)
        self.model.eval()

    def predict(self, text):
        """Predict language, intent, and entities for input text."""
        inputs = self.tokenizer(text, return_tensors="pt", truncation=True, max_length=128)
        inputs = {k: v.to(self.device) for k, v in inputs.items()}

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

        # Extract predictions from custom model heads
        # (Implementation depends on your model architecture)

        return {
            'language': 'detected_language',
            'intent': 'detected_intent',
            'entities': {}
        }

# Initialize
model = IntentityAIBA()

# Predict
text = "Transfer 12.5mln USD to Apex Industries account 27109477752047116719"
result = model.predict(text)
print(result)
```
