Abstract:

Systems and methods are provided for predicting rare events, such as hospitalization events. A set of data records, each containing multiple attributes with one or more values (which may include an “unknown” value), may represent a root node of a decision tree. This root node may be partitioned based on one of the attributes, such that the concentration (e.g., “purity”) of a relevant outcome (e.g., the rare event) is increased in one node and decreased in another. This process may be repeated until a decision tree with sufficiently pure leaf nodes is created. This “purified” decision tree may then be used to predict one or more rare events.

Abstract:

A method for storing data includes the steps of receiving a metadata parameter from a first user, the parameter being associated with a property in a database containing a plurality of data records, and storing the parameter. The method also includes the step of providing a second user with access to the stored parameter, the second user having an access level to the database which is different from that of the first user.
