Title: Machine learning-based decision support systems for personalized medical care

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.
