predict_KMeans {ClusterR}

Prediction function for the k-means

Description

Prediction function for the k-means

Usage

predict_KMeans(data, CENTROIDS, threads = 1, fuzzy = FALSE)

## S3 method for class 'KMeansCluster'
predict(object, newdata, fuzzy = FALSE, threads = 1, ...)

Arguments

data

matrix or data frame

CENTROIDS

a matrix of initial cluster centroids. The rows of the CENTROIDS matrix should be equal to the number of clusters and the columns should be equal to the columns of the data.

threads

an integer specifying the number of cores to run in parallel

fuzzy

either TRUE or FALSE. If TRUE, then probabilities for each cluster will be returned based on the distance between observations and centroids.

object, newdata, ...

arguments for the 'predict' generic

Details

This function takes the data and the output centroids and returns the clusters.

Value

a vector (clusters)

Examples

data(dietary_survey_IBS)

dat = dietary_survey_IBS[, -ncol(dietary_survey_IBS)]

dat = center_scale(dat)

km = KMeans_rcpp(dat, clusters = 2, num_init = 5, max_iters = 100, initializer = 'kmeans++')

pr = predict_KMeans(dat, km$centroids, threads = 1)
