Lizia-Mean

Module to do k-mean, the name is for mu daughter.

Install

npm install --save lizia-mean

Usage

const data = []
for (var i = 0; i < 14; i++) {
    data.push(Math.random() * 100);
}
const numClusters = 3
const dimensionOfData = 2
liziaMean(data, dimensionOfData, numClusters, (err, res) =>{
    assert(!err)
    console.log(res) //

API lizia-mean(data = [], dim = 1, numClusters = 1, cb) -> Array

data = [
       x_1, x_2, x_dim,
       ... ,
       ... ,
       x_Nx(dim-1),.., x_Nxdim
       ] // data are parsed by dim value

dimensionOfData = number to do parse the data array

numClusters = number of cluster to calculate

cb = callback called with error and response.

response = [
  data_set_1,  // data set inside of cluster 1
  data_set_2,
  ...,
  data_set_numClusters,
  cluster_1, // coords of cluster 1
  cluster_2,
  ...,

]

data_set_n = [
    y_1, y_2, y_dim,
       ... ,
       ... ,
    y_kx(dim-1),.., y_kxdim
]

with k the number of data in cluster n.
cluster_n = [z_1, z_2, ... , z_dim]
