# K-nearest neighbors algorithm and M-tree

## Difference between K-nearest neighbors algorithm and M-tree

### K-nearest neighbors algorithm vs. M-tree

In pattern recognition, the k-nearest neighbors algorithm (k-NN) is a non-parametric method used for classification and regression. M-trees are tree data structures that are similar to R-trees and B-trees.

## Similarities between K-nearest neighbors algorithm and M-tree

K-nearest neighbors algorithm and M-tree have 1 thing in common (in Unionpedia): Metric (mathematics).

### Metric (mathematics)

In mathematics, a metric or distance function is a function that defines a distance between each pair of elements of a set.

### The list above answers the following questions

• What K-nearest neighbors algorithm and M-tree have in common
• What are the similarities between K-nearest neighbors algorithm and M-tree

## K-nearest neighbors algorithm and M-tree Comparison

K-nearest neighbors algorithm has 62 relations, while M-tree has 12. As they have in common 1, the Jaccard index is 1.35% = 1 / (62 + 12).
