Decision trees
Like expert system but on steroids.
One of the basic machine-learning algorithms. Each tree "knows" a limited number of classes.
For each element, the tree "asks" some questions and chooses the class most similar to the element.
An automatic data analysis method.
Dates back to Hoveland and Hunt.
decision tree
Go back to the [[AI Glossary]]
A model represented as a sequence of branching statements. For example, the following over-simplified decision tree branches a few times to predict the price of a house (in thousands of USD). According to this decision tree, a house larger than 160 square meters, having more than three bedrooms, and built less than 10 years ago would have a predicted price of 510 thousand USD.
A tree three-levels deep whose branches predict house prices.
Machine learning can generate deep decision trees.
