Methods and systems of classifying multiple properties simultaneously using a decision tree

Abstract

This application describes systems and methods of forming a decision tree that simultaneously classifies multiple properties of items, and systems and methods of using the decision tree to simultaneously predicting multiple unknown properties of an item. In one embodiment, the decision tree has a top generic layer of nodes that are generic to all properties, a middle K layer of nodes that split on a property type descriptor K, and a bottom specific layer of nodes that are specific to some properties. In addition to simultaneously predicting multiple properties of new items, the decision tree may also aid users in uncovering relationships between properties and in determining what descriptors may represent a generic quality, and what descriptors may represent property-specific activity.
