Expand description

A fitted k-means model.

Fields§

§centroids: Vec<f64>

k × p centroids, row-major.

§labels: Vec<usize>

Cluster assignment per input row.

§inertia: f64

Within-cluster sum of squared distances (the objective; lower is tighter).

§k: usize§p: usize§n_iter: usize§converged: bool
