Query: Identifying robust communities and multi-community nodes by combining
  top-down and bottom-up approaches to clustering   Biological functions are carried out by groups of interacting molecules,
cells or tissues, known as communities. Membership in these communities may
overlap when biological components are involved in multiple functions. However,
traditional clustering methods detect non-overlapping communities. These
detected communities may also be unstable and difficult to replicate, because
traditional methods are sensitive to noise and parameter settings. These
aspects of traditional clustering methods limit our ability to detect
biological communities, and therefore our ability to understand biological
functions.
  To address these limitations and detect robust overlapping biological
communities, we propose an unorthodox clustering method called SpeakEasy which
identifies communities using top-down and bottom-up approaches simultaneously.
Specifically, nodes join communities based on their local connections, as well
as global information about the network structure. This method can quantify the
stability of each community, automatically identify the number of communities,
and quickly cluster networks with hundreds of thousands of nodes.
  SpeakEasy shows top performance on synthetic clustering benchmarks and
accurately identifies meaningful biological communities in a range of datasets,
including: gene microarrays, protein interactions, sorted cell populations,
electrophysiology and fMRI brain imaging.
