🤖 AI Model Architecture

🧠 Machine Learning Pipeline

🌳 Random Forest Classifier

Our AI model uses a sophisticated Random Forest ensemble with the following specifications:

🎯 Model Configuration

RandomForestClassifier(
    n_estimators=100,      # 100 decision trees
    max_depth=10,          # Maximum tree depth
    min_samples_split=2,   # Min samples to split
    min_samples_leaf=1,    # Min samples in leaf
    random_state=42,       # Reproducibility
    n_jobs=-1              # Parallel processing
)

🧪 Testing the AI Model

🔬 Comprehensive Testing Guide

Option 1: Web Interface Testing ⭐ Recommended

# Start the Flask server
python app.py

# Open browser to http://localhost:5000

Interactive Dashboard Features:

🗺️ Select state and district from dropdowns
🔘 Click "Analyze Risk" button
📊 View real-time predictions
🎲 See confidence scores
📈 Examine feature importance
💡 Get actionable recommendations

Option 2: Command Line Testing

Create test_model.py:

from flood_model import FloodRiskModel

# Initialize and train model
model = FloodRiskModel("path/to/rainfall_data.csv")
model.train()

# Test prediction
result = model.predict("Assam", "Kamrup Metro (Guwahati)")

# Display results
print("\n" + "="*50)
print("🌊 JALRAKSHAK FLOOD RISK PREDICTION")
print("="*50)
print(f"\n📍 Location: {result['state']} - {result['district']}")
print(f"\n🎯 Risk Level: {result['risk_level']}")
print(f"🎲 Confidence: {result['confidence']:.2f}%")
print(f"✅ Model Accuracy: {result['model_accuracy']:.2f}%")

print(f"\n📊 All Risk Probabilities:")
for risk, prob in result['all_probabilities'].items():
    bar = "█" * int(prob / 5)
    print(f"  {risk:8} [{bar:20}] {prob:5.2f}%")

print(f"\n🌧️ Rainfall Data:")
for key, value in result['rainfall_data'].items():
    print(f"  • {key}: {value}")

print(f"\n💡 Recommendations:")
for rec in result['recommendations']:
    print(f"  ✓ {rec}")
print("="*50)

Run it:

python test_model.py

Option 3: Load Pre-trained Model

After the first run, the model is saved. Load it directly:

from flood_model import FloodRiskModel

# Load existing model (no retraining needed)
model = FloodRiskModel("path/to/rainfall_data.csv")
model.load_model('flood_model.pkl')

# Make instant predictions
districts = [
    ("Assam", "Kamrup Metro (Guwahati)"),
    ("Assam", "Dibrugarh"),
    ("Meghalaya", "East Khasi Hills"),
]

for state, district in districts:
    result = model.predict(state, district)
    print(f"{district}: {result['risk_level']} ({result['confidence']:.1f}%)")

📋 Sample Test Cases

🟢 Low Risk

State: "Assam"
District: "Kamrup Metro"

Expected:
• Risk: LOW
• Confidence: 85%+
• Reason: Normal rainfall

🟡 Medium Risk

State: "Assam"
District: "Barpeta"

Expected:
• Risk: MEDIUM
• Confidence: 70-85%
• Reason: Elevated rainfall

🔴 High Risk

State: "Assam"
District: "Dhemaji"

Expected:
• Risk: HIGH
• Confidence: 90%+
• Reason: Severe rainfall
