📰 Fake News Detection using Machine Learning

🎯 Objective

To develop a machine learning model that can accurately classify news articles as fake or real using Natural Language Processing (NLP) techniques. This solution aims to support media platforms, fact-checkers, and cybersecurity efforts in mitigating misinformation across the internet.

🔍 Overview

Misinformation is a global challenge, particularly on digital platforms where fake news can go viral in minutes. This project leverages Python, NLP, and ML algorithms to build a classification model capable of detecting misleading or false content. The model utilizes TF-IDF vectorization and Logistic Regression to analyze news headlines or body text and predict authenticity with high accuracy.

provides a real-world utility in promoting digital truth and transparency.

📚 About the Project

The dataset used contains thousands of news headlines labeled as fake or real. After cleaning the data, textual content is converted into a numerical format using TF-IDF Vectorization. Multiple machine learning classifiers are then trained and evaluated.

Key Models:

Logistic Regression

PassiveAggressiveClassifier

Naive Bayes

Support Vector Machines (SVM)

Final model achieved ~94% accuracy, demonstrating strong potential for real-world deployment.

🧠 Project Workflow
