  • Method and system for reducing a data set
    Patent number: 7805421
    Abstract: System and methods are provided for applying a dimensionality reduction process to a data set. The method includes obtaining a data set including a first set of variables and identifying collections of the first set of variables for replacement by a second set of variables. The method also includes replacing the collections of the first set of variables with the second set of variables and eliminating the first set of variables from the data set.
    Type: Grant

  • Method and system for determining a combined risk
    Publication number: 20090222248
    Abstract: A computer system for determining a combined risk is disclosed. The computer system has a memory, at least one input device, and a central processing unit in communication with the memory and the at least one input device. The central processing unit obtains diagnostic data and identifies a plurality of models for analyzing the diagnostic data. The central processing unit also associates each model with one of a plurality of time periods and calculates, for each time period using the associated model, a predicted risk. Further, the central processing unit determines the combined risk based on the predicted risk for each time period.

  • Method for simplifying a mathematical model by clustering data
    Publication number: 20090112533
    Abstract: A method for simplifying a mathematical model is disclosed. The method obtains a data set and identifies a plurality of variables within the data set. The method also performs a clustering analysis by dividing the data set into groups, where each group has a cluster center. The method further replaces the plurality of variables with a plurality of cluster distances. The method also uses the plurality of cluster distances as a plurality of independent variables in a model creation process.
