K-Means Clustering is one of the popular clustering algorithm. The goal of this algorithm is to find groups(clusters) in the given data. In this post we will implement K-Means algorithm using Python from scratch. K-Means Clustering K-Means is a very simple algorithm which clusters the data...
K-means clusteringTo start out we're going to implement and apply K-means to a simple 2-dimensional data set to gain some intuition about how it works. K-means is an iterative, unsupervised clustering algorithm that groups similar instances together into clusters. The algorithm starts by guessi...
In this article, we will go through the k-means clustering algorithm. We will first start looking at how the algorithm works, then we will implement it using NumPy, and finally, we will look at…

For this project, I implemented the Kmeans as well as the kmeans++ algorithm from scratch. I used five data sets to showcase some applications and results of those algorithms. Further, after uncovering the drawbacks of Kmeans, I implemented a ‘Spectral clustering’ using the random forest (...
Calinski-Harabasz Index Example in Python In this section we will go through an example of calculating the Calinski-Harabasz index for a K-Means clustering algorithm in Python. First, import the required dependencies: You can use any data with the code below. For simplicity we will ...
