\nData structured in the form of overlapping or non-overlapping sets is found in a variety of domains, sometimes explicitly but often subtly. For example, teams, which are of prime importance in industry and social science studies are “sets of individuals”; “item sets” in pattern mining of customer transactions are sets and for various types of analysis in language studies a sentence can be considered as a “set or bag of words”. Although building models and inference algorithms for structured data has been an important task in the fields of machine learning and statistics, research on “set-like” data still remains less explored. Relationships between pairs of elements can be modeled as edges in a graph. However, for modeling relationships that involve all members of a set, hyperedges in a Hypergraph are more natural representations. This talk describes analyzing complex group structured data from domains like social networks, customer transaction data and knowledge graphs, via the lens of Hypergraphs. Specifically:
