KNN (K-Nearest Neighbors) is Dead!

KNN is as good as dead! SourceWe’re living through an extinction-level event. No, not COVID19. I’m talking about the demise of the popular KNN algorithm that is taught in pretty much every Data Science course! Read on to find out what’s replacing this staple in every Data Scientists' toolkit. KNN BackgroundFinding “K” similar items to any given item is widely known in the machine learning communit

"Strictly speaking, ANNs are a class of algorithms in which a small number of errors are allowed during the NN search. But in a real-world C2C marketplace where the number of “real” neighbors is higher than the “K” nearest neighbors being searched, ANNs can achieve remarkable accuracy on par
