Knn in machine learning interview questions
WebApr 14, 2024 · The reason "brute" exists is for two reasons: (1) brute force is faster for small datasets, and (2) it's a simpler algorithm and therefore useful for testing. You can confirm that the algorithms are directly compared to each other in the sklearn unit tests. Make kNN 300 times faster than Scikit-learn’s in 20 lines! WebK-Nearest Neighbors is a supervised classification algorithm, while k-means clustering is an unsupervised clustering algorithm. While the mechanisms may seem similar at first, what this really means is that in order for K-Nearest Neighbors to work, you need labelled data you want to classify an unlabeled point into (thus the nearest neighbour part)
