Decision trees | Classification algorithms
An alternating decision tree (ADTree) is a machine learning method for classification. It generalizes decision trees and has connections to boosting. An ADTree consists of an alternation of decision nodes, which specify a predicate condition, and prediction nodes, which contain a single number. An instance is classified by an ADTree by following all paths for which all decision nodes are true, and summing any prediction nodes that are traversed. (Wikipedia).

The decision tree algorithm belongs to the family of supervised learning algorithms. Just like other supervised learning algorithms, decision trees model relationships, and dependencies between the predictive outputs and the input features. As the name suggests, the decision tree algorit

Full lecture: http://bit.ly/D-Tree Decision trees are compact and extremely fast at testing time. They can also handle missing values, and irrelevant attributes naturally. On the downside, they are restricted to axis-aligned splits of the data, and the algorithm is not guaranteed to find

This is just a short follow up to last week's StatQuest where we introduced decision trees. Here we show how decision trees deal with variables that don't improve the tree (feature selection) and how they deal with missing data. For a complete index of all the StatQuest videos, check out:
