The Algerian Forest Fire ML project represents an innovative application of machine learning techniques to predict fire occurrences in forest regions of Algeria. By leveraging data science, cloud computing, and predictive modeling, this open-source initiative creates a powerful tool that could help in early warning systems and resource allocation for fire prevention and management.

Project Overview

The Algerian Forest Fire ML project is a comprehensive machine learning application developed by Tejas K (GitHub: tejask0512) that focuses on predicting forest fire occurrences based on meteorological data and other environmental factors. Deployed as a cloud-based application, this project demonstrates how data science can be applied to critical environmental challenges.

Technical Architecture

The project employs a robust technical stack designed for accuracy, scalability, and accessibility:

• Programming Language: Python
• ML Frameworks: Scikit-learn for modeling, Pandas and NumPy for data manipulation
• Web Framework: Flask for API development
• Frontend: HTML, CSS, JavaScript
• Deployment: Cloud-based deployment (likely AWS, Azure, or similar platforms)
• Version Control: Git/GitHub

The architecture follows a classic machine learning pipeline pattern:

1. Data ingestion and preprocessing
2. Feature engineering and selection
3. Model training and evaluation
4. Model deployment as a web service
5. User interface for prediction input and result visualization

Dataset Analysis

At the heart of the project is the Algerian Forest Fires dataset, which contains records of fires in the Bejaia and Sidi Bel-abbes regions of Algeria. The dataset includes various meteorological measurements and derived indices that are critical for fire prediction:

Key Features in the Dataset

The project demonstrates sophisticated data analysis techniques, including:

1. Exploratory Data Analysis (EDA): Thorough examination of feature distributions, correlations, and relationships with fire occurrences
2. Data Cleaning: Handling missing values, outliers, and inconsistencies
3. Feature Engineering: Creating derived features that might enhance predictive power
4. Statistical Analysis: Identifying significant patterns and trends in historical fire data

# Conceptual example of EDA in the project
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns

# Load dataset
df = pd.read_csv('Algerian_forest_fires_dataset.csv')

# Analyze correlations between features and fire occurrence
correlation_matrix = df.corr()
plt.figure(figsize=(12, 10))
sns.heatmap(correlation_matrix, annot=True, cmap='coolwarm')
plt.title('Feature Correlation Matrix')
plt.savefig('correlation_heatmap.png')

# Analyze seasonal patterns
monthly_fires = df.groupby('month')['Fire'].sum()
plt.figure(figsize=(10, 6))
monthly_fires.plot(kind='bar')
plt.title('Fire Occurrences by Month')
plt.xlabel('Month')
plt.ylabel('Number of Fires')
plt.savefig('monthly_fire_distribution.png')

X = df.drop('Fire', axis=1)
y = df['Fire']
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.25, random_state=42)

# Train Random Forest model
rf_model = RandomForestClassifier(n_estimators=100, random_state=42)
rf_model.fit(X_train, y_train)

# Evaluate model
y_pred = rf_model.predict(X_test)
print(classification_report(y_test, y_pred))

# Visualize confusion matrix

    'Feature': X.columns,
    'Importance': rf_model.feature_importances_
}).sort_values('Importance', ascending=False)

    # Determine prediction and confidence
    prediction = 1 if probabilities[1] > 0.5 else 0
    confidence = probabilities[1] if prediction == 1 else probabilities[0]
    
    return {
        'prediction': 'Fire Risk' if prediction == 1 else 'No Fire Risk',
        'confidence': round(confidence * 100, 2),
        'probability_distribution': {
            'no_fire': round(probabilities[0] * 100, 2),
            'fire': round(probabilities[1] * 100, 2)
        }
    }

Risk Level Classification

    df_new['temp_lag_3'] = df_new['Temperature'].shift(3)
    
    # Create rolling average features
    df_new['temp_rolling_3'] = df_new['Temperature'].rolling(window=3).mean()
    df_new['humidity_rolling_3'] = df_new['RH'].rolling(window=3).mean()
    
    # Create rate of change features
    df_new['temp_roc'] = df_new['Temperature'].diff()
    df_new['humidity_roc'] = df_new['RH'].diff()
