# lora_intent_classifier_roberta-base_model

## Model Description

This is a LoRA (Low-Rank Adaptation) fine-tuned model based on **roberta-base** for Intent Classification - Classifies text into categories like business, technology, science, etc..

This model is part of the [semantic-router](https://github.com/vllm-project/semantic-router) project and is optimized for use with the Candle framework in Rust.

## Model Details

- **Base Model**: roberta-base
- **Task**: Intent Classification
- **Framework**: Candle (Rust)
- **Model Size**: ~476MB
- **LoRA Rank**: N/A
- **LoRA Alpha**: N/A
- **Target Modules**: 

## Usage

### With semantic-router (Recommended)

```python
from semantic_router import SemanticRouter

# The model will be automatically downloaded and used
router = SemanticRouter()
results = router.classify_batch(["Your text here"])
```

### With Candle (Rust)

```rust
use candle_core::{Device, Tensor};
use candle_transformers::models::bert::BertModel;

// Load the model using Candle
let device = Device::Cpu;
let model = BertModel::load(&device, &config, &weights)?;
```

## Training Details

This model was fine-tuned using LoRA (Low-Rank Adaptation) technique:

- **Rank**: 16
- **Alpha**: 32 
- **Dropout**: 0.1
- **Target Modules**: 

## Performance

Intent Classification - Classifies text into categories like business, technology, science, etc.

For detailed performance metrics, see the [training results](https://github.com/vllm-project/semantic-router/blob/main/training-result.md).
