Prof. Toroczkai discussed Jaynes’s maximum entropy method that provides a family of principled models that allow the prediction of a system’s properties as constrained by empirical data (observables). However, their use is often hindered by the degeneracy problem characterized by spontaneous symmetry breaking, where predictions fail. In the talk Prof. Toroczkai showed that...

Alaa Mousawi presented today a talk on "CARP Model for Multi-Risk Dynamics" authored by him, Xiang Niu, Noemi Derzsy, Xin Lin, Gyorgy Korniss, Boleslaw K. Szymanski at APS March Meeting 2018 in Los Angeles, CA. Surprisingly little is known about how risk materializations in distinct domains influence each other. We present an approach in which expert assessments of likelihoods and...

Referring to the recently accepted paper in the IEEE Computer, the Army Research Laboratory states in their website article; that Army and university scientists are turning to problems with social media to create social sensing as a scientific discipline. For the Army in particular, this emerging science space, they say, will better help commanders assess and comprehend the...
