In this paper we propose a method to extract an abstracted floor plan from typical grid maps using Bayesian reasoning.

In this paper, we propose a generalizable method that systematically combines data driven MCMC samplingand inference using rule-based context knowledge for data abstraction.

In this paper, we propose a generalizable knowledge framework for data abstraction, i. e. finding compact abstract model for input data using predefined abstract terms.

The primary challenge for any autonomous system operating in realistic, rather unconstrained scenarios is to manage the complexity and uncertainty of the real world.

Our approach to generate scene graphs is probabilistic: Uncertainty in the object poses is addressed by a probabilistic sensor model that is embedded in a data driven MCMC process.
