About the Event

Networks are everywhere! They provide a powerful way to detect patterns and relationships within big data systems. But, are they meaningful when the “system” is an individual person? Indeed, the reliability and validity of network approaches have been questioned in the social and medical sciences; network results are assumed to generalize across people and time, but these assumptions rarely hold because people are heterogeneous and dynamic. The goal of this presentation is to introduce a person-specific perspective to network modeling, and to illustrate the accuracy of a particular modeling approach called group iterative multiple model estimation (GIMME). Two novel GIMME-related applications will also be presented. In the first, GIMME will be used to detect individualized time-varying neural connectivity during a resting state, revealing connectivity parameters that are associated with cognitive impulsivity. In the second, GIMME will be used to identify personalized links among emoji-based emotion structures and daily depressive symptomatology. This is an ongoing work with possible extensions to big(ger) data (e.g., Twitter) and with implications for precision health care.
