K-Means Clustering Tool: Cluster numeric points by iterative nearest-centroid assignment and arithmetic centroid updates. Farthest-point deterministic initialization avoids random results.
When to use K-Means Clustering
Use this clustering method to explore structure in numeric observations after selecting a meaningful feature representation, distance or similarity measure, and algorithm-specific controls.
- points
- Required list input.
- clusters
- Required integer input.
- max Iterations
- Required integer input.
How K-Means Clustering works
Cluster numeric points by iterative nearest-centroid assignment and arithmetic centroid updates. Farthest-point deterministic initialization avoids random results. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- centroids
- The resulting centroids returned as a list.
- labels
- The resulting labels returned as a list.
- iterations
- The resulting iterations returned as an integer.
Limitations and assumptions
- Clusters are model-dependent rather than ground truth. Scaling, outliers, dimensionality, initialization, stopping criteria, density variation, and hyperparameters can materially change the partition.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Standardize features when appropriate, repeat stochastic runs, inspect cluster stability and diagnostics, and compare another algorithm whose assumptions differ. Validate usefulness against the downstream question rather than cluster count alone.

Fit fuzzy c-means memberships that sum to one across clusters for each point; fuzzifier must exceed one.

Shift each point to the mean of points within a fixed Euclidean bandwidth, then merge nearby modes. Bandwidth controls the number of modes.
