A method for data sensitive filtering in a patient database searches includes providing a search criteria comprising one or more search locator fields, determining a retrieval formula from the search criteria that maximizes error tolerance in the search criteria while satisfying a predefined response time requirement, and retrieving candidate records from the database. If no retrieval formula can be found that satisfies the response time requirements, the method includes requesting additional search criteria, scoring each candidate record by comparing a search criteria locator field with a corresponding retrieved record field, and determining whether the score of the candidate record exceeds a predefined threshold. If the candidate score does exceed the threshold, the candidate record is added to a list of records to be returned in response to the search criteria.

A method for predicting survival rates of medical patients includes providing a set D of survival data for a plurality of medical patients, providing a regression model having an associated parameter vector &#x3b2;, providing an example xof a medical patient whose survival probability is to be classified, calculating a parameter vector {circumflex over (&#x3b2;)} that maximizes a log-likelihood function of &#x3b2; over the set of survival data, l(&#x3b2;|D), wherein the log likelihood l(&#x3b2;|D) is a strictly concave function of &#x3b2; and is a function of the scalar x&#x3b2;, calculating a weight wfor example x, calculating an updated parameter vector &#x3b2;* that maximizes a function l(&#x3b2;|D&#x222a;{(y,x,w)}), wherein data points (y,x,w) augment set D, calculating a fair log likelihood ratio &#x3bb;from {circumflex over (&#x3b2;)} and &#x3b2;* using &#x3bb;=&#x3bb;(&#x3b2;*|x)+sign(&#x3bb;({circumflex over (&#x3b2;)}|x)){l({circumflex over (&#x3b2;)}|D)&#x2212;l(&#x3b2;*|D)}, and mapping the fair log likelihood ratio &#x3bb;to a fair price y, wherein said fair price is a probability that class label yfor example xhas a value of 1.

System and method for medical predictive models using likelihood gamble pricing

A system and method for optimizing database access for record linkage by tiling the space of record pairs are provided, the system including a processor, a segmentation and pairing unit in signal communication with the processor for segmenting database data into data segments and pairing the data segments into data quadrants, and a duplicate detection unit in signal communication with the processor for detecting duplicates for each quadrant; and the method including receiving database data, segmenting the database data into data segments, pairing the data segments into data quadrants, and detecting duplicates for each quadrant.
