🔧 Configuration
Edit config.py to customize:

Model Settings: Change supported models and languages
Processing Limits: Adjust batch sizes and memory limits
UI Themes: Modify color schemes
Cache Settings: Configure caching parameters

📊 Supported Models

English: CardiffNLP Twitter RoBERTa
Multilingual: CardiffNLP XLM-RoBERTa
Chinese: UER RoBERTa Chinese

🎨 Themes

Default: Green/Red/Orange
Ocean: Blue/Orange/Cyan
Dark: Darker variants
Rainbow: Purple/Pink/Red

⚡ Performance Features

Model Caching: LRU cache for efficient model management
Parallel Processing: Multi-threaded batch analysis
Memory Optimization: Automatic cleanup and GPU management
Lazy Loading: Models loaded on-demand

🐛 Troubleshooting
Common Issues

SHAP/LIME Errors: Reduce sample size or text length
Memory Issues: Lower batch size or enable text cleaning
Model Loading: Check internet connection for model downloads
Port Conflicts: Change port in main.py if 7860 is occupied

Performance Tips

Use GPU if available for faster processing
Enable text cleaning for better preprocessing
Reduce sample sizes for faster explainable AI analysis
Clear history periodically to save memory
