Dissertation
Title: Machine learning-based decision
support systems for personalized medical care
Advisor: Associate Professor W.
Nick Street
Brief description: This dissertation describes three new algorithms
for constructing machine learning-based decision support systems. All three
acquire and update medical knowledge automatically from data and utilize
nonlinear forms of knowledge to provide personalized decision support. These
new methods are applied to: (1) individualized multi-objective hospital
referral that estimates personalized survival probabilities in each hospital
and facilitates more flexible and better hospital selection; (2) individualized,
cost-effective diagnosis that determines individualized testing sequences to
speed up diagnoses and reduce testing cost without losing diagnostic
performance; (3) individualized lifestyle recommendation that constructs
patient-specific lifestyle changes based on the individual characteristics to
reduce the risk of cardiovascular disease.
