Center node: "simultaneous localization and layout model selection in manhattan worlds"
  Abstract: In this letter, we will demonstrate how Manhattan structure can be exploited to transform the simultaneous localization and mapping problem, which is typically solved by a nonlinear optimization over feature positions, into a model selection problem solved by a convex optimization over higher-order layout structures, namely walls, floors, and ceilings. Furthermore, we show how our novel formulation leads to an optimization procedure that automatically performs data association and loop closure and which ultimately produces the simplest model of the environment that is consistent with the available measurements. We verify our method on real-world data sets collected with various sensing modalities.

Connected through hyperedge HE-1 (induced by source paper "predictive and semantic layout estimation for robotic applications in manhattan worlds"):
