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 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)

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)

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 :
