Returns the index of the nearest centroid to x without updating the model.

Usage

kmeans_stream_predict(model, x)

Arguments

model

a streaming k-means model created by kmeans_stream_new

x

a numeric vector of length d

Value

integer, the cluster assignment for x (1-indexed)

#> [1] 2
kmeans_stream_predict(model, c(0.1, 0.1))
