Phi-3 Sustainable Materials Classifier

Fine-tuned Phi-3-mini-4k-instruct model for classifying sustainable materials from product descriptions.

Model Description

This model is a LoRA fine-tuned version of Microsoft's Phi-3-mini-4k-instruct, specifically trained to identify and classify sustainable materials in product descriptions. It can recognize:

Renewable Materials: Cork, Bamboo, Wood, Stone Paper, Kraft Paper, Wheat Straw, Bio-Based Plastics, and more
Recycled Materials: Recycled PET, RPET Polyester, Recycled Paper/Cardboard, Recycled Cotton, and more
Certifications: GRS Certified, RCS Certified, AWARE™, REPREVE

Intended Use

Product sustainability analysis
E-commerce material classification
Environmental compliance checking
Sustainable sourcing verification

How to Use

Using Hugging Face Inference API

python

import requests

API_URL = "https://api-inference.huggingface.co/models/YOUR_USERNAME/phi3-sustainable-materials"
headers = {"Authorization": "Bearer YOUR_HF_TOKEN"}

def classify_material(product_name):
    prompt = f"""Below is product data. Classify the sustainable material.

### Input:
Product: {product_name}

### Response:
"""
    
    response = requests.post(API_URL, headers=headers, json={
        "inputs": prompt,
        "parameters": {
            "max_new_tokens": 256,
            "temperature": 0.7,
            "return_full_text": False
        }
    })
    return response.json()

# Example
result = classify_material("Recycled Cardboard Notebook")
print(result)

Expected Output Format

json

{
  "material_name": "Recycled Cardboard",
  "reason": "Product explicitly mentions recycled cardboard material",
  "confidence": "100% confident",
  "confidence_level": "high"
}

Training Data

Trained on a custom dataset of product descriptions with sustainable material annotations, covering:

Product names and descriptions
Material types and classifications
Confidence levels and reasoning

Training Procedure

Base Model: microsoft/Phi-3-mini-4k-instruct
Fine-tuning Method: LoRA (Low-Rank Adaptation)
LoRA Rank: 16
Target Modules: q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj
Training Epochs: 3
Learning Rate: 2e-4
Max Sequence Length: 2048
Prompt Format: Alpaca instruction format

Limitations

Optimized for English product descriptions
Best performance on explicitly mentioned materials
May require additional context for generic sustainability claims
Confidence levels are model-predicted and should be validated
