The department in Lund was founded in 1988 by professor Peter Gärdenfors and presently houses three postdocs and fifteen Ph.D. students. n order to understand how humans form new ideas and how machines could be made to learn new concepts, one needs adequate models of concept formation. Within cognitive science, symbolic models have competed with concept learning in neural networks. At LUCS, the focus is instead on the dimensions that make up concepts. Using 'conceptual spaces', the aim is to develop models of concept formation that are more psychologically realistic than the symbolic, and that allow faster learning than neural networks.
