Some example use cases might be finding articles about similar subjects or audiences for news recommendations, finding songs or movies with similar descriptors, or finding documents that are similar to a search query. We’ll only scratch the surface of this class of algorithms, but we’ll present some nice pedagogical development for simple implementations.
