Implementing K-Means++ Algorithm in Python: Step-by-Step Guide

K-Means++ is an improvement over the original K-Means algorithm that helps in choosing better initial cluster centers, reducing the chance of converging to suboptimal solutions. Here’s a step-by-step guide to implementing K-Means++ in Python:

Step 1: Import the necessary libraries

import numpy as np
import matplotlib.pyplot as plt
from sklearn.datasets import make_blobs

• The first line imports the NumPy library, which is a fundamental package for scientific computing in Python.
• The second line imports the pyplot module from the Matplotlib library, which is a plotting library in Python.
• The third line imports the make_blobs function from the datasets module of the scikit-learn library.

Step 2: Generate some synthetic data using the make_blobs function from scikit-learn

X, _ = make_blobs(n_samples=500, centers=4, random_state=42)
