🌍 Waste Recognition Model for Environmental Sustainability

Overview

The Waste Recognition Model is a deep-learning-based solution designed to classify various types of waste materials with high accuracy. By integrating AI-powered waste classification, this project aims to enhance waste management efficiency, reduce environmental pollution, and promote sustainable waste disposal practices.

Key Features

• Accurate Waste Classification: Identifies waste materials across multiple categories.
• Disposal Recommendations: Suggests proper disposal methods to minimize environmental impact.
• Real-Time Processing: Provides quick and efficient waste recognition for seamless integration into waste management systems.
• User-Friendly Interface: Accessible via a web-based application.
• Versatile Deployment: Can be used in homes, offices, and industrial waste management systems.
• Environmental Impact: Reduces contamination and promotes sustainable waste disposal.

Waste Categories

The model is trained to classify waste into the following categories:

1. Plastic Waste - Bottles, wrappers, straws, bags.
2. Metal Waste - Aluminum, copper, iron, steel.
3. Organic Waste - Food waste, yard waste.
4. Glass Waste - Bottles, jars, containers.
5. Electronic Waste - Computers, phones, appliances.
6. Textile Waste - Clothing, fabric materials.
7. Medical Waste - Clinical and medical items.
8. Wood Waste - Construction wood, furniture.
9. Paper Waste - Newspapers, magazines, cardboard.
10. Shoes Waste - Footwear and related items.

Data Preparation

• Dataset Collection: Waste images are gathered from multiple sources, ensuring diverse and well-distributed data.
• Preprocessing: Images undergo resizing, normalization, and augmentation to enhance model generalization.
• Labeling: Data is labeled into predefined categories.
• Splitting: The dataset is divided into training, validation, and testing sets for model evaluation.

Model Training

• Architecture: The model is built using Fastai with a ResNet34 backbone for transfer learning.
• Optimization: Fine-tuned using techniques such as learning rate finder and gradual unfreezing.
• Training: The model undergoes multiple epochs of training to minimize loss and improve accuracy.
• Evaluation Metrics: Accuracy, loss, and confusion matrix are used to assess performance.

Inference

• Model Deployment: The trained model is deployed on Gradio and Hugging Face for easy accessibility.
• User Interaction: Users upload waste images, and the model predicts the waste category and provides disposal guidance.
• Real-Time Testing: The inference pipeline processes new images with minimal latency, making it efficient for practical applications.
