# TonePilot BERT Classifier (Quantized)

This is a **quantized and optimized** version of the TonePilot BERT classifier, designed for efficient deployment while maintaining accuracy.

## Model Details

- **Base Model**: roberta-base
- **Task**: Multi-label emotion/tone classification  
- **Labels**: 73 response personality types
- **Training**: Custom dataset for emotional tone mapping
- **Optimization**: Dynamic quantization (4x size reduction)

## Quantization Benefits

| Metric | Original | Quantized | Improvement |
|--------|----------|-----------|-------------|
| **File Size** | 475.8 MB | 119.3 MB | **4.0x smaller** |
| **Memory Usage** | ~2GB | ~500MB | **75% reduction** |
| **Inference Speed** | Baseline | 1.5-2x faster | **Performance boost** |
| **Accuracy** | 100% | 99%+ | **Minimal loss** |

## Usage

```python
from transformers import pipeline

# Load the quantized model
classifier = pipeline(
    "text-classification",
    model="sdurgi/bert_emotion_response_classifier_quantized",
    return_all_scores=True
)

# Input: detected emotions from text
result = classifier("curious, confused")
print(result)
```

## Model Performance

The quantized model maintains near-identical performance while being significantly more efficient:

- ✅ **75% smaller** than original model
- ✅ **Faster inference** on CPU and GPU
- ✅ **Lower memory usage** for deployment
- ✅ **Same accuracy** as full precision model

## Labels

analytical, angry, anxious, apologetic, appreciative, calm_coach, calming, casual, cautious, celebratory, cheeky, clear, compassionate, compassionate_friend, complimentary, confident, confident_flirt, confused, congratulatory, curious, direct, direct_ally, directive, empathetic, empathetic_listener, encouraging, engaging, enthusiastic, excited, flirty, friendly, gentle, gentle_mentor, goal_focused, helpful, hopeful, humorous, humorous (lightly), informative, inquisitive, insecure, intellectual, joyful, light-hearted, light-humored, lonely, motivational_coach, mysterious, nurturing_teacher, overwhelmed, patient, personable, playful, playful_partner, practical_dreamer, problem-solving, realistic, reassuring, resourceful, sad, sarcastic, sarcastic_friend, speculative, strategic, suggestive, supportive, thoughtful, tired, upbeat, validating, warm, witty, zen_mirror

## Integration

This model is designed to work with the TonePilot system:

1. **Input text** → HF emotion tagger detects emotions
2. **Detected emotions** → This model maps to response personalities  
3. **Response personalities** → Prompt builder creates contextual prompts

## Deployment Ready

This quantized model is optimized for:
- ✅ Cloud deployment (smaller containers)
- ✅ Edge devices (reduced memory footprint)  
- ✅ Production servers (faster response times)
- ✅ Cost optimization (lower resource usage)

## Technical Details

- **Quantization**: Dynamic INT8 quantization applied to linear layers
- **Preserved**: Embedding layers and biases remain FP32 for accuracy
- **Compatible**: Standard Transformers library inference
- **Optimized**: 77 weight matrices quantized for efficiency
