Recommender Systems Complete Course Beginner to Advanced - Machine Learning for Recommender Systems: Exploring Genres in

The video tutorial covers data cleaning and analysis techniques on a movie dataset. It begins by introducing variables and handling missing genres, followed by dropping entries without genres to enhance data quality. The tutorial then demonstrates replacing lines in the genres column with spaces for consistency. It proceeds to count the occurrences of each genre using nested loops and visualizes the results with a bar plot using matplotlib. The tutorial concludes with a brief mention of calculating term frequency and inverse document frequency.
