K-Nearest Neighbours and K-Means Clustering

4.1. K-Nearest Neighbours and K-Means Clustering#

In this lesson we’ll be looking at more machine learning techniques:

  • K-nearest neighbours regressor - supervised learning

  • K-nearest neighbours classifier - supervised learning

  • K-means clustering - unsupervised learning

The core concept underpinning these models is the idea that the distance between datapoints is a measure of similarity.
