Kyosuke Tanaka’s paper accepted to #ComplexNetworks2018 conference

SONIC research graduate, Kyosuke will be traveling to Cambridge, UK for the Complex Networks 2018 conference. A paper by Kyosuke Tanaka and Agnes Horvat, an Assistant Professor in Communication Studies at Northwestern, has been accepted and will also be included in the conference proceedings.
Their paper, titled “Network Strategies and Efficiency in Human Communication Networks,” explains the effect of networking strategies on efficiency in communication networks. Tanaka and Horvat use data-driven computer simulations to examine how manipulations in the form of added, deleted, strengthened and weakened communication channels alter the local and global efficiency of communication networks. Their results indicate that there is a clear trade-off between networking strategies and efficiency. Their findings reassess conventional wisdom about the effectiveness of networking strategies.

Complexity Explorables by Dirk Brockmann

Complexity Explorables is a website where people easily explore some complex systems examples while playing models with fun.

For example, “I herd you!” enables you to explore how different network structures impact the spread of a disease in a population. Consequently, you can understand a phenomenon called “herd immunity”, defined that “a disease can be eradicated even if not the entire population is immunized.” The webpage is simple, yet very informative.

If you’re interested, there are many other examples and models. Check them out at http://www.complexity-explorables.org/explorables/!

Cameron DeChurch & Noshir Contractor will present their paper in Cambridge

SONIC summer research intern Cameron DeChurch will be traveling to Cambridge, UK to present his paper at the Complex Networks 2018 conference. This summer he used historical records to construct digital networks of the collaboration among Florentine Renaissance painters. His paper with Noshir Contractor, “Using Network Science to Discover the Grand Masters of the Florentine Renaissance” finds that rather than the household names of Michelangelo and DaVinci, it was the grand masters like Verrochio and Perugino who ultimately had more impact through their lineage, by training painters who would go on to produce great works.

Generative Modeling of Human Behavior and Social Interactions Using Abductive Analysis

Abstract:

Abduction is an inference approach that uses data and observations to identify plausible (and preferably, best) explanations for phenomena. Applications of abduction (e.g., robotics, genetics, image understanding) have largely been devoid of human behavior. Here, we devise and execute an iterative abductive analysis process that is driven by the social sciences: behaviors and interactions among groups of human subjects. One goal is to understand intra-group cooperation and its effect on fostering collective identity. We build an online game platform; perform and analyze controlled laboratory experiments; form hypotheses; build, exercise, and evaluate network-based agent-based models; and evaluate the hypotheses in multiple abductive iterations, improving our understanding as the process unfolds. While the experimental results are of interest, the paper’s thrust is methodological, and indeed establishes the potential of iterative abductive looping for the (computational) social sciences.
