🎓 Student Success Prediction Dashboard

A beautiful Streamlit application that predicts student academic outcomes (Graduate, Dropout, or Enrolled) using a Random Forest model trained on 36 features including academic performance, demographics, and economic indicators.

🚀 Quick Start

1. Train and Save the Model

First, run the training script to create the pickle files:

python train_and_save_model.py

This will create:

• random_forest_model.pkl - The trained Random Forest model
• preprocessing_info.pkl - Preprocessing pipeline information
• feature_names.pkl - Feature names for consistency

2. Install Dependencies

pip install -r requirements.txt

3. Launch the Dashboard

streamlit run streamlit_app.py

The dashboard will open in your browser at http://localhost:8501

📊 Model Performance

• Algorithm: Random Forest Classifier (n_estimators=100)
• Training Accuracy: 100%
• Test Accuracy: 93.84%
• Features: 36 student characteristics
• Classes: Graduate (50%), Dropout (32%), Enrolled (17%)

🎯 Features

Complete Input Form

• Personal Information: Marital status, gender, age, nationality
• Academic Background: Application details, course, previous qualifications
• Family Background: Parents' education and occupation
• Financial & Social: Scholarships, debts, special needs status
• Academic Performance: 1st and 2nd semester curricular units and grades
• Economic Indicators: Unemployment rate, inflation rate, GDP

Beautiful Interface

• Responsive Design: Clean, professional layout with custom CSS
• Interactive Widgets: User-friendly dropdowns with human-readable labels
• Real-time Predictions: Instant results with confidence scores
• Visual Analytics: Interactive charts showing prediction probabilities
• Model Insights: Performance metrics and key factors display

Accurate Preprocessing

• Exact Pipeline Match: Preprocessing mirrors the training notebook exactly
• One-hot Encoding: Categorical variables properly encoded
• Feature Consistency: Ensures all 105+ features match training data
• Input Validation: Handles missing features and maintains column order

🔧 Technical Details

Data Pipeline

1. Data Loading: Reads from ./data/data.csv
2. Column Cleaning: Removes apostrophes, fixes typos (Nacionality → Nationality)
3. Target Encoding: Maps Dropout=0, Enrolled=1, Graduate=2
4. One-hot Encoding: Converts categorical features to binary columns
5. Feature Alignment: Ensures prediction input matches training features

Model Architecture

• Random Forest with 100 estimators
• No scaling required (tree-based model)
• Train/Test Split: 70/30 with random_state=42
• Cross-validation: 5-fold validation during training

User Experience Enhancements

• Human-readable Labels: Maps numeric codes to descriptive text
• Smart Defaults: Pre-filled with typical student values
• Interactive Sliders: Easy input for numeric values
• Color-coded Results: Green for Graduate, Red for Dropout, Yellow for Enrolled
• Confidence Display: Shows probability scores for all three outcomes
