Knowledge Hypergraphs

Hypergraphs are a generalization of graphs (mathematical objects that represent networks), that allow for the representation of complex information structures, namely human knowledge and natural language communication. By employing modern Natural Language Processing techniques and general knowledge ontologies and databases, it becomes possible to transform free-form text into formal structures that are convenient both for […]

Scales of Human Movement

Human mobility is known to be distributed across several orders of magnitude of physical distances, which makes it difficult to find or define typical and meaningful scales. Relying on geotagged data collected from photo-sharing social media, we apply community detection to movement networks constrained by increasing percentiles of the distance distribution. We discover clear phase […]

Philosophy of AI

There is overwhelming evidence that human intelligence is a product of Darwinian evolution. Investigating the consequences of self-modification, and more precisely, the consequences of utility function self-modification, leads to the stronger claim that not only human, but any form of intelligence is ultimately only possible within evolutionary processes. Human-designed artificial intelligences can only remain stable […]

Network Generators and Artificial Scientists

Models explaining network morphology and growth processes permit a wide range of phenomena to be more systematically analyzed and understood. At the same time, creating such models is often challenging and requires insights that may be counter-intuitive. We have developed an approach to automatically detect realistic decentralized network growth models from empirical data, employing a […]

Evolutionary Multi-Agent Simulations

Advances in fields such as Complexity Science and Artificial Life enable a modern direction in Computational Intelligence research. Instead of building isolated artificial intelligence systems from the top-down, this approach attempts to design systems where a population of agents and the environment interact and adaptation processes take place. We created a novel artificial brain model, […]
