WebK-mean is an unsupervised learning technique (no dependent variable) whereas KNN is a supervised learning algorithm (dependent variable exists) K-mean is a clustering technique which tries to split data points into K-clusters such that the points in each cluster tend to be near each other whereas K-nearest neighbor tries to determine the ... WebJul 19, 2024 · KNN is a supervised classification algorithm that classifies new data points based on the nearest data points. On the other hand, K-means clustering is an unsupervised clustering algorithm that groups data into a K number of clusters. How does KNN work? As mentioned above, the KNN algorithm is predominantly used as a classifier.
