Fake News Detection Using Machine Learning

📌 Overview

This project focuses on building a Fake News Detection System using machine learning and natural language processing (NLP) techniques. By analyzing and classifying textual data, the system aims to accurately distinguish between fake and real news. The project utilizes various machine learning models, evaluates their performance, and includes robust visualizations to understand data and results effectively.

🛠️ Features

• Preprocessing: Cleaning text data, generating word counts, character counts, and sentiment polarity scores.
• Visualization: Word clouds, distribution plots, and interactive graphs for data exploration.
• Balanced Dataset: Utilizes SMOTE for oversampling to handle class imbalance.
• Model Training: Trains and compares multiple models:
  • Logistic Regression
  • Multinomial Naive Bayes
  • Random Forest Classifier
• Metrics: Detailed evaluation using accuracy, precision, recall, F1 score, ROC-AUC score, and confusion matrices.
