🎭 Vietnamese Sentiment Analysis

A Vietnamese sentiment analysis web interface built with Gradio and transformer models, optimized for Hugging Face Spaces deployment.

🚀 Features

• 🤖 Transformer-based Model: Uses 5CD-AI/Vietnamese-Sentiment-visobert from Hugging Face Hub
• 🌐 Interactive Web Interface: Real-time sentiment analysis via Gradio
• ⚡ Memory Efficient: Built-in memory management and batch processing limits
• 📊 Visual Analysis: Confidence scores with interactive charts
• 📝 Batch Processing: Analyze multiple texts at once
• 🛡️ Memory Management: Real-time memory monitoring and cleanup

🎯 Usage

Single Text Analysis

1. Enter Vietnamese text in the input field
2. Click "Analyze Sentiment"
3. View the sentiment prediction with confidence scores
4. See probability distribution in the chart

Batch Analysis

1. Switch to "Batch Analysis" tab
2. Enter multiple Vietnamese texts (one per line)
3. Click "Analyze All" to process all texts
4. View comprehensive batch summary with sentiment distribution

Memory Management

• Monitor real-time memory usage
• Use "Memory Cleanup" button if needed
