Comprehension and appropriateness of complex mobile pictographs for crisis communication
In crisis situations, illiterates and people with other linguistic challenges are unable to understand text messages to inform or be informed of a situation. Pictographic interfaces have been proposed as a sol...

Generating Adaptive Route Instructions Using Hierarchical Reinforcement Learning
We present a learning approach for efficiently inducing adaptive behaviour of route instructions. For such a purpose we propose a two-stage approach to learn a hierarchy of wayfinding strategies using hierarch...

Spatial Abstraction: Aspectualization, Coarsening, and Conceptual Classification
Spatial abstraction empowers complex agent control processes. We propose a formal definition of spatial abstraction and classify it by its three facets, namely aspectualization, coarsening, and conceptual clas...

Generalization and Transfer Learning in Noise-Affected Robot Navigation Tasks
When a robot learns to solve a goal-directed navigation task with reinforcement learning, the acquired strategy can usually exclusively be applied to the task that has been learned. Knowledge transfer to other...

Qualitative Spatial Representation and Reasoning in the SparQ-Toolbox
A multitude of calculi for qualitative spatial reasoning (QSR) have been proposed during the last two decades. The number of practical applications that make use of QSR techniques is, however, comparatively sm...
