Description

Tune clustering hyperparameters by evaluating an intrinsic metric over a parameter grid and selecting the elbow (max curvature).

Usage

Value

returns a clu_tune object.

Arguments

base_model

base model for tuning

folds

number of folds for cross-validation

ranges

a list of hyperparameter ranges to explore

model <- clu_tune(cluster_kmeans(k = 0), ranges = list(k = 1:10))

model <- fit(model, iris[,1:4])
model$k
