Title: SYSTEM AND METHOD FOR IDENTIFYING SUSPICIOUS HEALTHCARE BEHAVIOR
Abstract:
Aspects of the disclosed technology include a method including receiving, by a processor, first healthcare data including a first plurality of features of a plurality of candidate profiles; identifying, by the processor, a profile calculation window; creating, by the processor, a reference profile of the first healthcare data over the profile calculation window by dimensionally reducing the first plurality of features, the reference profile including a normal subspace and a residual subspace; analyzing, by the processor, the residual subspace of the reference profile; and detecting, based on the analyzed residual subspace, suspicious behavior of one or more first candidate profiles of the plurality of candidate profiles based on a deviation of the one or more first candidate profiles within the residual subspace from an expected profile.
