Nearest Neighbors Recommendation Engine / The Coding Train

Nearest Neighbors, Part 1This sketch shows how to calculate a similarity score between two users.
Nearest Neighbors, Part 2This sketch iterates through all the users to find the "nearest neigbors" and list "similar" users.
Nearest Neighbors, Part 3This sketch uses the K-Nearest Neighbor Machine Learning algorithm to predict ratings for movies that haven't been seen yet.
Nearest Neighbors, Part 3 with added stylingThis sketch has added styling.

In this multi-part coding challenge, I create a movie recommendation engine using the "nearest neighbor" algorithm.
