  • Process database entries to provide predictions of future data values
    Patent number: 6725210
    Abstract: The present invention relates to a method and apparatus for processing entries stored in an electronic database where each entry comprises a succession of data values of correlated variables. The entries are processed in order to provide predictions of future data values of the correlated variables. The invention has particular application to processing data entries that relate to customers of a bank or retail business so as to predict future data values of attributes of the customers. A prior distribution over the parameters of a first of the variables is accessed from the database and data values of the first variable are used to derive a posterior distribution of the parameters of the first variable. A prior distribution over the parameters of a second of the variables is accessed from the database, the second of the variables being correlated with the first. Data values of the second variable are accessed to derive a posterior distribution of the parameters of the second variable.

  • Optimizing database entries
    Patent number: 6671679
    Abstract: A data processing apparatus is operated to optimize the amount of information represented by entries in a database. The operation comprises forming prior distributions over the parameters of entries in the database and subjecting a potential entry for the database to a process of evaluation. The evaluation includes, (a) sampling parameters from the prior distributions, (b) calculating a utility function from the samples and from the potential entry, and (c) calculating a utility value from the utility function. The process of evaluation is repeated for each of a plurality of further potential entries and the potential entry having the highest calculated utility value is selected.
