K-d tree

Clustering 3: overview of methods

Full lecture: http://bit.ly/K-means In this course we cover 4 different clustering algorithms: K-D trees (part of lecture 9), K-means (this lecture), Gaussian mixture models (lecture 17) and agglomerative clustering (lecture 20).

KD tree algorithm: how it works

[http://bit.ly/k-NN] K-D trees allow us to quickly find approximate nearest neighbours in a (relatively) low-dimensional real-valued space. The algorithm works by recursively partitioning the set of training instances based on a median value of a chosen attribute. When we get a new data in

Graph Theory: 36. Definition of a Tree

In this video I define a tree and a forest in graph theory. I discuss the difference between labelled trees and non-isomorphic trees. I also show why every tree must have at least two leaves. An introduction to Graph Theory by Dr. Sarada Herke. Related Videos: http://youtu.be/zxu0dL436gI

Part 1: background and behaviour on regular trees Part 2: limit theorems for lattice first-passage times For many lattice models in probability, the high-dimensional behaviour is well-predicted by the behaviour of a corresponding random model defined on a regular tree. Rigorous results
