Methods to analyse the pair-wise connectivity of data in the temporal domain can provide a rich framework with which to extract transient, dynamic information. This paper presents a theoretical framework for a novel and highly flexible method to this end. By constructing a graph encoding the topology of connectivity, we expound upon a general theory for graph functions which allow for novel temporal probing of the connectivity information, defined as ‘temporal connectivity’. This includes… CONTINUE READING
