Python In Practice - 15 Projects to Master Python - Extracting Features and Transforming the Reviews Data

The video tutorial covers the process of feature extraction from text data, specifically reviews and ratings. It begins with dividing data into input and output, followed by creating vectors using CountVectorizer. The tutorial explores vocabulary and feature names extracted from the text data. It then applies TF-IDF transformation to the features and prepares the data for model training, focusing on converting reviews into a digital format and associating them with ratings.
