In K-Means, each cluster is associated with a centroid. The main objective of the K-Means algorithm is to minimize the sum of distances between the points and their respective cluster centroid.1. The data/vector points closest to the hyperplane (black line) are known as the support vector (SV) data points because only these two points are contributing to the result of the algorithm (SVM), other points are not. 2. If a data point is not an SV, removing it has no effect on the model. 3.Analytics Vidhya is a community of Analytics and Data Science professionals.
