Being a data science enthusiast (which you are since you’re reading this), you must have come across quite a number of K prefixed phrases like k means, k modes, k nearest neighbors, and so on and…

How to determine the optimal K for K-Means?

Analytics Vidhya

The K-Means algorithm needs no introduction. It is simple and perhaps the most commonly used algorithm for clustering. The basic idea behind k-means consists of defining k clusters such that total…

K-Means Explained

Towards Data Science

This article will outline a conceptual understanding of the k-Means algorithm and its associated python implementation using the sklearn library. K means is a clustering algorithm with many use cases…...

Get the Optimal K in K-Means Clustering

Towards AI

Clustering (or Cluster Analysis) helps to identify and group the data points, which is closely related using some measure of distance, to a blob of data or segment. Clustering is classified as…

How Important is the K in KNN Algorithm

Towards Data Science

K-nearest neighbors (KNN) is a supervised machine learning algorithm that can be used to solve both classification and regression tasks. It is based on a very simple idea. The value of a data point…

K-Means Step-by-Step

Level Up Coding

Clustering algorithms help group data into groups or clusters that are similar. There are a number of different approaches to clustering. In this post, we look at one of the most popular clustering…

K-Means Simplified

Towards AI

Clustering is the process of grouping a set of data objects (or observations) into subsets. Each subset is a cluster, such that objects in a cluster are similar to one another but different from…

K as in Keras…simple classification model!

Towards Data Science

Hope you have an idea what this post is all about, yes you are right! It’s about building a simple classification model using Keras API. As we all know Keras is one of the simple,user-friendly and…

Choosing the Best K Value for K-means Clustering

Analytics Vidhya

There are many machine learning algorithms used for different applications. Some of them are called “supervised” and some are “unsupervised”. Today, we will be talking about an unsupervised…
