Function kmedoids::random_initialization

pub fn random_initialization(
    n: usize, 
    k: usize, 
    rng: &mut impl Rng
) -> Vec<usize>

Random initialization (requires the rand crate)

This is simply a call to rand::seq::index::sample.

• n - size of the data set
• k - number of clusters to find
• rng - random number generator

returns a vector of medoid indexes in 0..n-1

Example

Given a dissimilarity matrix of size n x n, use:

let mut meds = kmedoids::random_initialization(10, 2, &mut rand::thread_rng());
println!("Chosen medoids: {:?}", meds);
