WebSep 11, 2024 · Kmeans algorithm is an iterative algorithm that tries to partition the dataset into K pre-defined distinct non-overlapping subgroups (clusters) where each data point belongs to only one group. It tries to make the inter-cluster data points as similar as possible while also keeping the clusters as different (far) as possible. WebThe k-means problem is solved using either Lloyd’s or Elkan’s algorithm. The average complexity is given by O (k n T), where n is the number of samples and T is the number of iteration. The worst case complexity is given by O (n^ … imperx t4840

"WebI am trying to find the 'best' value of k for k-means clustering by using a pipeline where I use a standard scaler followed by custom k-means which is finally followed by a Decision Tree classifier. I am then trying to use this pipeline for a Grid Search to get the best value of k. Python 3.7 and sklearn are being used. " - Cystanford/kmeansgithub.com

WebMar 26, 2024 · KMeans is not a classifier. It is unsupervised, so you can't just use supervised logic with it. You are trying to solve a problem that does not exist: one does not use KMeans to post existing labels.
