Privacy-preserving seedbased data synthesis
How can we share sensitive datasets in such a way as to maximize utility while simultaneously safeguarding privacy? This thesis proposes an answer to this question by re-framing the problem of sharing sensitive datasets as a data synthesis task. Specifically, we propose a framework to synthesize …

Detecting Bots using Stream-based System with Data Synthesis
… the continuous supply of representative labeled data, which are expensive and time-consuming to obtain in practice. In this thesis, we build a bot detection system with a data synthesis method to explore detecting bots with limited data to address this problem. We collected the network traffic …

Data synthesis : a comprehensive visual approach to material selection in architecture
… means to distill, organize, and select relevant data. Material databases and the enabling power of the internet can only be exploited as "information providers" for designers when such a system is adapted. Material selection has been identified as a means of exploring this type of analysis / …

TECHNOLOGICAL BREAKTHROUGH TOWARDS THE USE OF A NOVEL VISUAL-INERTIAL ODOMETRY SYSTEM AS AN AID FOR THE DIGITALLY-GUIDED INTERVENTION
Recent data availability of three dimensional imaging brought new possibilities for the guided intervention. The management of complex data requires the use of new tools and new technologies. We analyzed the use of algorithms for the automatic, ai-driven segmentation to extrapolate the best systems …

Distribution distance measures in generative and privacy models
… models. In both cases, the goal is to simulate a data distribution without revealing too much about individual points. While early generative models focused on matching data in a component-wise manner, the models in this work incorporate distribution metrics to provide population-level information …

Analyzing longitudinal patterns of river metabolism in five distinct rivers
… river health and functioning. This analysis is a data synthesis to examine longitudinal coherence in productivity patterns and identify the strongest controls that disrupt coherence. I find that between discharge, dissolved oxygen, and metabolism, metabolism is the least predictable variable going …

Reading to Learn
… are trained on vast quantities of annotated data or experience. These systems often do not generalize to new, related problems that emerge after training, such as conversing about new topics or interacting with new environments. This thesis introduces Reading to Learn, a new class of …

The Role of the Clinical Nurse Leader in Reintroducing and Sustaining a Successful Cancer Risk Assessment Program in a Community Hospital Setting
… identification of downstream revenue sources. Data analysis includes historical patient volume, screening and procedural reimbursement rates, population statistics and organization market share, and program financial impacts. Data synthesis reveals a CRA program demonstrates potential revenue …

Instrumentation and Control of a Ducted Fan Unmanned Aerial Vehicle in Hover Mode
… found from system identification based on flight data. Synthesis of a linear state feedback controller based on this model is discussed, and it is demonstrated in hardware that this controller can effectively stabilize the vehicle.

Understanding the role of plant hydraulic traits in ecological processes
… treatments. In Chapter 3, I performed a data synthesis to study how environment and evolutionary history shape plant hydraulic trait variation among evergreen and deciduous species across the world tropics. Through this pantropical data synthesis, I was able to point out biases in the …

A new approach in data visualization to integrate time and space variability of daylighting in the design process
… The way existing daylighting tools deliver data to designers is still inefficient. The output display has no quick switch between quantitative and qualitative data and simply considers single moments with fixed weather condition. Designers are interrupted in their design process, and they …

Closing the gap: a review of factors affecting quality improvement interventions at the primary care level
… The objectives of this review are to identify, synthesise and evaluate research literature relevant to primary care regarding quality improvement interventions; as well as identify the enabling and constraining factors impacting quality improvement at the primary care level. Design: This review …

Data combining using mixtures of g-priors with application on county-level female breast cancer prevalence
As more and more data are available, data synthesis has become an indispensable task for researchers. From a Bayesian perspective, this dissertation includes three related projects and aims at quantifying the benefits of combining data under various scenarios in terms of the theoretical properties …

Self-harm and suicidality among lesbian, gay, bisexual, and trans youth : the role of school-based connectedness
… The systematic review comprised a narrative data synthesis of 15 relevant studies. Findings of this review indicated that school connectedness is associated with improvements in the mental health of LGBT youths, whilst evidence regarding the influence of teacher connectedness was mixed. The …

Automatic Behavioral Analysis from Faces and Applications to Risk Marker Quantification for Autism
… framework to calibrate a trained deep model with data synthesis and augmentation. First we focus on pose-invariant facial expression recognition. It is known that 3D features have higher discrimination power than 2D features; however, usually 3D features are not readily available at testing time. …
