WebJun 11, 2024 · The idea of the K-Means algorithm is to find k centroid points (C_1, C_1, . . . C_k) by minimizing the sum over each cluster of the sum of the square of the distance between the point and its centroid. This cost is NP-hard and has exponential time complexity. So we use the idea of approximation using Lloyd’s Algorithm. Lloyd’s Algorithm: WebMar 1, 2024 · We provide uniform concentration bounds on the kernel k-means clustering objective based on Rademacher complexity by posing the underlying problem as a risk minimization task.This approach results in state-of-the-art convergence rates on the excess risk besides the eventual establishment of strong consistency of cluster centers.
