DARPA SocialSim: Deep Agent: A Framework for Information Spread and Evolution in Social Networks


For this project, we will build a comprehensive, realistic and at-scale computational simulation of information spread and evolution in online social networks using a novel computational modeling paradigm: Deep Agent Framework (DAF). The Deep Agent Framework unleashes the power of combining massively parallel computing, data analytics of large datasets and machine learning into assisting model designers to mix and match sub models in a semi-automated way, exploring, testing and validating not one but tens of thousands of models against not a single real world phenomenon but a large set of target behaviors. This process will aid model designers to continuously improve the best-so-far model as the problem challenges become more difficult. In fact, this process would also serve to automatically recombine and introduce variants to all the models produced by different TA1 performers in order to obtain the overall best model. This framework will enable the creation of an accurate and at-scale simulation of information spread and evolution that can run on a typical off-the shelf commercial computer or small cluster.
Partially as a result of this project, the Inverse Generative Social Science (iGSS) community was formed: Inverse Generative Social Science Workshop 2021, Inverse Generative Social Science Workshop 2021.
