A Framework for the Time- and Frequency-Domain Assessment of High-Order Interactions in Brain and Physiological Networks
脑与生理网络高阶交互的时域和频域评估框架
While the standard network description of complex systems is based on quantifying links between pairs of system units, higher-order interactions (HOIs) involving three or more units play a major role in governing the collective network behavior. This work introduces an approach to quantify pairwise and HOIs for multivariate rhythmic processes interacting across multiple time scales. We define the so-called O-information rate (OIR) as a new metric to assess HOIs for…
