Novel Two-Dimensional Visualization Approaches for Multivariate Centroids of Clustering Algorithms
| Input: Number of the centroids, k | | Output: Set of the final centroids, C | | Begin | | ≔ Randomly selected element in I | | : Set of the initial centroids | | Y: Set of the distances between and the closest element to in | | y: Length of Y | | Add into | | Add the distance between and the closest element to in , into Y | | Repeat | | For i = 1 : y | | U ≔ U + | | u ≔ A random real number between 0 and U | | p ≔ 2 | | Repeat | | U ′≔ 0 | | For i = 1 : p − 1 | | U ′≔ U′ + | | p ≔ p + 1 | | Until U ≥ u > U′ | | Add Ip−1 into | | Add the distance between Ip−1 and the closest element to Ip−1 in , into Y | | Until has k centroids | | Run the standard K-means with | | Return C returned from the standard K-means | | End |
