Add Streamlit app for student success prediction and model training script

- Created `streamlit_app.py` for a user-friendly dashboard to predict student outcomes using a Random Forest model. - Added `requirements.txt` to specify necessary Python packages for the application. - Implemented `train_and_save_model.py` to train the Random Forest model and save it along with preprocessing information. - Included detailed user input forms for various student characteristics and academic performance metrics. - Added custom styling for better UI/UX in the Streamlit app. - Integrated prediction results display with probability metrics and model performance insig

+# 🎓 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:
+
+```bash
+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
+
+```bash
+pip install -r requirements.txt
+```
+
+### 3. Launch the Dashboard
+
+```bash
+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
