Python for Machine Learning - The Complete Beginners Course - K-Nearest Neighbors Algorithm

The video tutorial explains the concept of similarity between two classes using a visual example. It introduces the Kehne classifier, which assigns a new data point to a category based on the highest number of similar neighbors. The tutorial also covers the Euclidean distance formula, which is used to calculate the distance between two points and identify the nearest neighbor.

Describe the relationship between the categories A&B and the new data point in the context of similarity.
