MovieLens Data Analysis. Each title as a row, each age group as a column, and the average rating in each cell. Of course men like Terminator more than women. All the variables given are categorical, LibFM gave good results in this challenge. MovieLens 100K Dataset. MovieLens 1M Stable benchmark dataset. MovieLens 100k dataset. MovieLens 20M movie ratings. Keras is a Python library for deep learning that wraps the efficient numerical libraries Theano and TensorFlow. Additionally, because our columns are now a MultiIndex, we need to pass in a tuple specifying how to sort. Building a Movie Recommendation Engine session is part of Machine Learning Career Track at Code Heroku. # the movies file contains columns indicating the movie's genres, # let's only load the first five columns of the file with usecols, Practical pandas by Tom Augspurger (one of the pandas developers). The datasets describe ratings and free-text tagging activities from MovieLens, a movie recommendation service. 100,000 ratings from 1000 users on 1700 movies. We're splitting the DataFrame into groups by movie title and applying the size method to get the count of records in each group. What Will You Learn. * Each user has rated at least 20 movies. Because movie_stats is a DataFrame, we use the sort method - only Series objects use order. Stable benchmark dataset. Click the Data tab for more information and to download the data.
