Similar to PCA, matrix factorization (MF) technique attempts to decompose a (very) large matrix (\(m \times n\)) to smaller matrices (e.g. Your Amazon Personalize model will be trained on the MovieLens Latest Small dataset that contains 100,000 ratings and 3,600 tag applications applied to 9,000 movies by 600 users. In order to making a recommendation system, we wish to training a neural network to take in a user id and a movie id, and learning to output the user’s rating for that movie. However, rather than downloading this dataset and placing the data that we care about in the /dropbox directory, we will use NiFi to pull the data directly from the MovieLens site.
