🚀 Hugging Face Spaces Setup Guide

Overview

This guide explains how to create a Hugging Face Space for interactive testing of the StoxChai NSE Stock Prediction Models.

What We're Creating

• Interactive Web App: Users can test models directly on Hugging Face
• Real-time Predictions: Input 16 features and get stock price predictions
• Model Comparison: See predictions from all 8 models side-by-side
• Beautiful UI: Modern Gradio interface with gradients and styling

Step-by-Step Setup

1. Create Hugging Face Space

1. Go to huggingface.co/spaces
2. Click "Create new Space"
3. Choose settings:
   • Owner: thoutam
   • Space name: stoxchai-stock-predictor
   • Space SDK: Gradio
   • Space hardware: CPU (free tier)
   • License: MIT

2. Upload Files

Upload these files to your Space:

Core Files:

• app.py - Main Gradio application
• requirements_app.txt - Python dependencies
• All 8 trained models (.joblib files)
• feature_scaler.joblib - Feature scaler

Documentation:

• README.md - Main documentation
• model_card.md - Model information
• Generated visualization images

3. Configure Space

The Space will automatically:

• Install dependencies from requirements_app.txt
• Run app.py as the main application
• Create a web interface at https://huggingface.co/spaces/thoutam/stoxchai-stock-predictor

Features of the Interactive App

🎯 Model Testing

• 8 Models Available: RandomForest, GradientBoosting, LinearRegression, Ridge, Lasso, SVR, XGBoost, LightGBM
• Real-time Predictions: Get instant stock price predictions
• Feature Input: 16 input fields for technical indicators
• Sample Data: Pre-filled with example values

📊 Results Display

• Individual Predictions: See results from each model
• Ensemble Prediction: Average of all successful predictions
• Error Handling: Graceful handling of prediction failures
• Formatted Output: Clean, readable results

🎨 User Interface

• Modern Design: Beautiful gradients and styling
• Responsive Layout: Works on desktop and mobile
• Intuitive Controls: Easy-to-use input forms
• Helpful Descriptions: Clear feature explanations

Usage Instructions

For Users

1. Visit the Space: Navigate to your Hugging Face Space URL
2. Input Features: Enter 16 technical indicators
3. Select Model: Choose which model to use
4. Get Prediction: Click "Make Prediction" button
5. Compare Results: View predictions from all models

For Developers

1. Clone the Space: Download the Space repository
2. Modify App: Customize the Gradio interface
3. Add Features: Extend functionality as needed
4. Deploy Updates: Push changes to automatically update

Technical Details

Dependencies

• Gradio: Web interface framework
• Scikit-learn: Machine learning models
• Joblib: Model persistence
• NumPy/Pandas: Data processing

Model Loading

• Models are loaded when the app starts
• Feature scaler is applied automatically
• 5-day lookback sequences are created dynamically
• Error handling for missing model files

Input Validation

• Checks for exactly 16 features
• Validates numeric input types
• Handles missing or invalid data gracefully

Customization Options

UI Styling

• Modify CSS in the create_interface() function
• Change color schemes and gradients
• Adjust layout and spacing
• Add custom themes

Model Selection

• Add/remove models from the dropdown
• Change default model selection
• Add model descriptions and metadata

Feature Inputs

• Modify feature names and descriptions
• Add input validation rules
• Change default sample values
• Add feature help text

Troubleshooting

Common Issues

1. Models Not Loading: Check file paths and permissions
2. Prediction Errors: Verify input feature format
3. Memory Issues: Use smaller models or CPU optimization
4. Dependency Errors: Check requirements.txt compatibility

Debug Mode

• Enable show_error=True in app.launch()
• Check Space logs for error messages
• Test locally before deploying

Benefits of Hugging Face Spaces
