Movie Recommendations with k-Nearest Neighbors and Cosine Similarity

---

Introduction

The k-nearest neighbors (k-NN) algorithm is among the simplest algorithms in the data mining field. Distances / similarities are calculated between each element in the data set using some distance / similarity metric ^^[1]^ that the researcher chooses (there are many distance / similarity metrics), where the distance / similarity between any two elements is calculated based on the two elements' attributes. A data element’s k-NN are the k closest data elements according to this distance / similarity.

---

1. A distance metric measures distance; the higher the distance the further apart the neighbors. A similarity metric measures similarity; the higher the similarity the closer the neighbors.

Approaching a Xamarin.Android Bindings Case

1. Investigation

One of the best ways to investigate a problematic Xamarin.Android Binding is to first ensure you have the proper tooling available:

• Diagnostic MSBuild Output Enabled(Instructions)
• Java Decompiler(http://jd.benow.ca/)
• .NET Decompiler(https://www.jetbrains.com/decompiler/)
• Binding SDK Documentation
