This document describes a project that uses an LSTM recurrent neural network to detect fake news. It trains the LSTM model on a dataset of past news labeled as genuine or fake. The news texts are converted to TF-IDF vectors using n-grams before training. The trained model achieves 69.49% accuracy on the test data at predicting whether a new piece of news text is genuine or fake. Screenshots demonstrate data preprocessing, model training and evaluation, and testing the model on new news texts.

We downloaded available twitter FAKE NEWS tweets from internet and below is the dataset screen shots In above dataset we can see last two columns contains news text and target value where text contains news data and target contain class label as 0 and 1 where 0 means that news is GENUINE and 1 means thatnewsisFAKE. In belowscreen we are showing code that using NGRAMto convert news data to TF-IDF vector

Inabove screenshowingsome recordsfrom total 7612 news records and in bottom lines we can see dataset contains total 7613 records and then application using 80% (6090 news records) for training and then using 20% (1523 news records) for testing and now dataset is ready with numeric record and

After building model when we gave any news text then LSTM will check whether more words belongs to genuine or fake category and whatever category get more matching percentage then application will predict that class label.
