From Free Text to Clusters of Content in Health Records: An Unsupervised Graph Partitioning Approach
M. Tarik Altuncu, Erik Mayer, Sophia N. Yaliraki +1
Electronic Healthcare records contain large volumes of unstructured data in different forms. Free text constitutes a large portion of such data, yet this source of richly detailed…
Approximations of countably-infinite linear programs over bounded measure spaces
Juan Kuntz, Philipp Thomas, Guy-Bart Stan +1
We study a class of countably-infinite-dimensional linear programs (CILPs) whose feasible sets are bounded subsets of appropriately defined spaces of measures. The optimal value, o…
Global Network Prediction from Local Node Dynamics
Neave O'Clery, Ye Yuan, Guy-Bart Stan +1
The study of dynamical systems on networks, describing complex interactive processes, provides insight into how network structure affects global behaviour. Yet many methods for net…
Collective search with finite perception: transient dynamics and search efficiency
Adam Gosztolai, Jose A. Carrillo, Mauricio Barahona
Motile organisms often use finite spatial perception of their surroundings to navigate and search their habitats. Yet standard models of search are usually based on purely local se…
Content-driven, unsupervised clustering of news articles through multiscale graph partitioning
M. Tarik Altuncu, Sophia N. Yaliraki, Mauricio Barahona
The explosion in the amount of news and journalistic content being generated across the globe, coupled with extended and instantaneous access to information through online media, m…
From Text to Topics in Healthcare Records: An Unsupervised Graph Partitioning Methodology
M. Tarik Altuncu, Erik Mayer, Sophia N. Yaliraki +1
Electronic Healthcare Records contain large volumes of unstructured data, including extensive free text. Yet this source of detailed information often remains under-used because of…
Structured networks and coarse-grained descriptions: a dynamical perspective
Michael T. Schaub, Jean-Charles Delvenne, Renaud Lambiotte +1
This chapter discusses the interplay between structure and dynamics in complex networks. Given a particular network with an endowed dynamics, our goal is to find partitions aligned…
Multiscale dynamical embeddings of complex networks
Michael T. Schaub, Jean-Charles Delvenne, Renaud Lambiotte +1
Complex systems and relational data are often abstracted as dynamical processes on networks. To understand, predict and control their behavior, a crucial step is to extract reduced…
The exit time finite state projection scheme: bounding exit distributions and occupation measures of continuous-time Markov chains
Juan Kuntz, Philipp Thomas, Guy-Bart Stan +1
We introduce the exit time finite state projection (ETFSP) scheme, a truncation-based method that yields approximations to the exit distribution and occupation measure associated w…
