| Usage | Returns | ee.Clusterer.wekaXMeans(minClusters, maxClusters, maxIterations, maxKMeans, maxForChildren, useKD, cutoffFactor, distanceFunction, seed) | Clusterer |
| Argument | Type | Details | minClusters | Integer, default: 2 | Minimum number of clusters. |
maxClusters | Integer, default: 8 | Maximum number of clusters. |
maxIterations | Integer, default: 3 | Maximum number of overall iterations. |
maxKMeans | Integer, default: 1000 | The maximum number of iterations to perform in KMeans. |
maxForChildren | Integer, default: 1000 | The maximum number of iterations in KMeans that is performed on the child centers. |
useKD | Boolean, default: false | Use a KDTree. |
cutoffFactor | Float, default: 0 | Takes the given percentage of the split centroids if none of the children win. |
distanceFunction | String, default: "Euclidean" | Distance function to use. Options are: Chebyshev, Euclidean & Manhattan. |
seed | Integer, default: 10 | The randomization seed. |
