Machine learning systems now routinely use embeddings in thousands of dimensions to extract patterns from large-scale network data. Should we embrace this data revolution and let go of the simpler theories of yore—the likes of the S1 and Bradley-Terry models? In this talk, I will argue that low-dimensional embedding can find concise, interpretable patterns in networks and thus have a place in any modern data science stack. I will illustrate this point through a number of stories about social hierarchies and decision-making.
