AUTOMATIC DISEASE DIAGNOSES USING LONGITUDINAL MEDICAL RECORD DATA
First Claim
1. A method of automated medical diagnosis, the method comprising:
- obtaining an electronic longitudinal data set for each of a plurality of patients, wherein each data set comprises;
a plurality of measurement values corresponding to a metric, wherein each measurement value is associated with a respective time point,arranging the data sets into two or more clusters, wherein arranging the data sets comprises;
aligning the data sets according to their respective time points;
selecting a cluster center for each cluster;
determining a similarity between each data set and each cluster center;
assigning each data set to a particular cluster based on the similarities; and
iteratively re-aligning one or more of the data sets and/or reselecting one or more cluster centers, determining an updated similarity between each data set and each cluster center, and re-assigning data sets to particular clusters based on the updated similarities until a stop criterion is met; and
automatically determining a medical diagnosis for a patient based on a relationship between the patient'"'"'s data set and a cluster center.

Abstract
An example method of automated medical diagnosis includes obtaining an electronic longitudinal data set for each of a plurality of patients, where each data set includes a plurality of measurement values corresponding to a metric, where each measurement value is associated with a respective time point. The method also includes arranging the data sets into two or more clusters. Arranging the data sets includes aligning the data sets according to their respective time points, selecting a cluster center for each cluster, determining a similarity between each data set and each cluster center, assigning each data set to a particular cluster based on the similarities, and iteratively re-aligning one or more of the data sets and/or reselecting one or more cluster centers, determining an updated similarity between each data set and each cluster center, and re-assigning data sets to particular clusters based on the updated similarities until a stop criterion is met. The method also includes automatically determining a medical diagnosis for a patient based on a relationship between the patient'"'"'s data set and a cluster center.
