Outcome prediction and structure discovery in healthcare data
… We then turn to overcoming limitations in two clustering settings. In a semi-supervised setting, where pairwise constraints (relationships between pairs of points) are available, we develop an algorithm capable of performing accurate clustering under noisy constraints. This is achieved via soft …

Evolutionary cluster costing for weapon system early design
The Evolutionary Cluster Costing Methodology (ECCM) is proposed for estimating the cost of designing and producing a weapon system at the early design stage. The issue is related to the particular difficulties which system designers often encounter in the absence of cost data on present system …

Modeling Temporal and Spatial Data Dependence with Bayesian Nonparametrics
… are generated.</p> <p>Focused on model-based clustering and segmentation, this thesis addresses the issue in different ways, for temporal and spatial dependence.</p> <p>For sequential data analysis, the dynamic hierarchical Dirichlet process is proposed to capture the temporal dependence …

Complex data analytics via sparse, low-rank matrix approximation
… Decomposition (EMD), a novel method for fast clustering large-scale data by incorporating low-rank approximations into matrix decomposition-based clustering; 2) we propose ECKF, a general model for large-scale Evolutionary Clustering based on low-rank Kernel matrix Factorization; by monitoring …
