Active ACE Lab Projects

  • Signatures of communities and change – LDRD   Pacific Northwest National Labs
  • Scaling sociological models of influence to massive online social networks  UW Center for Commercialization
  • Simulation-based studies using the PhySense social activity simulator on the Exacycle platform  Google Exacycle
  • Scalable parallel graph analytics for dynamic graphs on the Intel Xeon Phi MIC architecture  Intel Parallel Computing Center Program

Our work is extensively based on PhySense, the ACE lab in-house extensible agent-based temporal event simulator. PhySense addresses signal propagation in networks characterized by non-linear models for node activity and edge interaction. The resulting data is post-processed by a suite of algorithms leading to several inter-related research themes.  PhySense serves as a social prototyping lab providing big synthetic data for driving theoretical and computational research and complements our associated research on real world data.

Active ACE Lab Research Directions

  • Building intelligence and decision making abilities into agents for PhySense
  • Multigraph and tensor representations for social, technological, and organizational networks
  • Scalable graph analytics and language abstractions on emerging computing architectures
  • Information theoretic measures of causal influence in dynamic activity-based networks
  • Stochastic models for agent behavior and interaction in PhySense
  • Scalable computation of  multigraph Green’s functions
