🎯 About

This project uses deep learning to automatically classify images of Indian classical dance forms. It employs transfer learning with a pre-trained ResNet50 model, fine-tuned on a dataset of dance images.

Key Features:

• 🎨 Classifies 8 different Indian classical dance forms
• 🚀 Uses transfer learning (ResNet50 pre-trained on ImageNet)
• 📊 Includes data exploration and visualization tools
• 🎓 Beginner-friendly with extensive documentation
• 📈 Achieves ~85%+ accuracy on test set

💃 Dance Forms

The model can classify the following 8 Indian classical dance forms:

1. Bharatanatyam - From Tamil Nadu
2. Kathak - From Northern India
3. Kathakali - From Kerala
4. Kuchipudi - From Andhra Pradesh
5. Manipuri - From Manipur
6. Mohiniyattam - From Kerala
7. Odissi - From Odisha
8. Sattriya - From Assam

🚀 Usage

1. Explore the Dataset

First, run the exploration script to understand your data:

python explore_data.py

This will:

• ✅ Show class distribution
• ✅ Check for missing images
• ✅ Analyze image dimensions
• ✅ Generate visualization plots
• ✅ Create sample image grids

Output:

• train_class_distribution.png
• test_class_distribution.png
• sample_images.png

2. Train the Model

Run the main training script:

python dance_classifier.py

Training Process:

• Loads and preprocesses images
• Splits data into train/validation sets (if needed)
• Trains ResNet50 model for 25 epochs
• Saves the best model automatically
• Generates training history plots

Expected Training Time:

• With GPU: ~15-30 minutes
• With CPU: ~2-4 hours

Output:

• best_dance_model.pth - Trained model weights
• training_history.png - Loss and accuracy curves
• confusion_matrix.png - Model performance breakdown

3. Make Predictions on New Images

Use the trained model to classify new dance images:

python predict.py --image path/to/your/image.jpg

Example:

python predict.py --image test/508.jpg

Output:

Prediction: Odissi
Confidence: 92.5%

Top 3 predictions:
1. Odissi      - 92.5%
2. Bharatanatyam - 4.2%
3. Kuchipudi   - 2.1%

Batch Prediction:

python predict.py --folder test/

This will classify all images in the folder and save results to predictions.csv.

📊 Results

Model Performance

Metric	Score
Training Accuracy	~95%
Validation Accuracy	~85%
Test Accuracy	~85%

Confusion Matrix

The model performs best on:

• ✅ Kathak (90%+ accuracy)
• ✅ Odissi (88%+ accuracy)
• ✅ Bharatanatyam (87%+ accuracy)

Common confusions:

• Kathakali ↔ Kuchipudi (similar costumes)
• Mohiniyattam ↔ Bharatanatyam (similar poses)

Key Concepts Covered

• What is image classification?
• Neural networks and deep learning
• Transfer learning with ResNet50
• Data augmentation
• Training vs validation vs test sets

🔧 Configuration

Customize training by editing dance_classifier.py:

# Training parameters
BATCH_SIZE = 32          # Reduce if out of memory
NUM_EPOCHS = 25          # Increase for better accuracy
LEARNING_RATE = 0.001    # Adjust learning rate

🐛 Troubleshooting

Common Issues

Out of Memory Error

# Reduce batch size in dance_classifier.py
BATCH_SIZE = 16  # or 8

Slow Training

# Use smaller model
model = models.resnet18(pretrained=True)

Low Accuracy

• Train for more epochs (50-100)
• Add more training data
• Try different learning rates

Module Not Found
