Meaning of K-Means Clustering

Simple definition

K-means clustering is an unsupervised machine learning algorithm that groups data points into a specified number of clusters based on their similarities.

How to use K-Means Clustering in a professional context

K-means is used in marketing to segment customers, in biology to classify species, and in finance to identify patterns in transaction data.

Concrete example of K-Means Clustering

An e-commerce company uses K-means to group customers based on purchase behavior, creating targeted marketing strategies for each cluster.

How does K-means clustering work?

It assigns data points to clusters by minimizing the distance between points and their cluster's centroid.

How is the number of clusters determined?

Techniques like the elbow method or silhouette score are used to choose the optimal number.

Can K-means handle non-numeric data?

Not directly; non-numeric data must be encoded or converted into numeric formats first.
