Thanks! There is a subtle difference. We define microclusters within the category of anomalous edge detection as 'suddenly arriving groups of suspiciously similar edges' e.g. denial of service attacks in network traffic data and lockstep behavior.

Subgraph detection on the other hand is detecting anomalous subgraphs and may also not be able to detect microclusters (suddenly arriving groups of suspiciously similar edges.)
