Measurement data sets of molecular biology and other experimental sciences are being collected comprehensively to openly accessible databases. This form of existing knowledge in quite complex, partly relevant and heterogeneous given that laboratories around the globe have different procedures to measure patient data. The research problem addressed in the thesis...

Title: Constraint-based Causal Discovery: Conflict Resolution with Answer Set Programming
 
Abstract: Recent approaches to causal discovery based on Boolean satisfiability solvers have opened new opportunities to consider search spaces for causal models with both feedback cycles and unmeasured confounders. However, the available methods have so far not been able to provide a principled account of...

Abstract:

The optimization of logistics in large building complexes with many resources, such as hospitals, requires realistic facility management and planning. Current planning practices rely foremost on manual observations or coarse unverified assumptions and therefore do not properly scale or provide realistic data to inform facility planning. In this talk I will present analysis methods to extract knowledge from large...

Further understanding of DNA hybridization kinetics has new urgency because recent DNA network systems often depends critically on hybridization rates particularly under isothermal conditions. Indeed, sequence-dependent decrease of performance for hybridization-based oligonucleotide networks has been reported, and the mechanism is still not understood....

Abstract:

Mobile phones are increasingly equipped with sensors, such as accelerometers, GPS receivers, proximity sensors and cameras, which can be used to sense and interpret people behaviour in real-time. Novel user-centered sensing applications can be built by exploiting the availability of these technologies. Moreover, data extracted from the sensors can also be used to model and predict people behaviour and movement...

Abstract: Smartphones are a pretty big deal. Many of us now begin our day with our phone’s alarm clock. On the way to work we read email while listening to music. We navigate to novel locations with instructions to turn left in 500 yards. At the end of the day, we relax by queueing up YouTube content on our phone to watch on the big screen television. All of this is done on a small...

Methods for Finding Interesting Nodes in Weighted Graphs

With the increasing amount of graph-structured data available, finding interesting objects, i.e., nodes in graphs, becomes more and more important. In this thesis we focus on finding interesting nodes and sets of nodes in graphs or networks. We propose several definitions of node interestingness as well as different methods to...
