Integrating landmarks into a computational model of early cognitive mapping

Gürgen, Erkan
This work aims to expand the computational theory of early cognitive mapping proposed by Yeap (1988) and Yeap and Jefferies (1999). Yeap and Jefferies developed a computational theory based on human cognitive mapping studies. Their theory starts from a 2 1/2-D sketch that is the output of Marr's vision theory (Marr, 1982). They attempt to answer the question of what is computed first from 2 1/2-D sketch. They argue that the boundary of the local space which one is surrounded by is computed first. Yeap and Jefferies' theory and implementations are limited with early cognitive mapping excluding landmark mknowledge. This work aims to improve the theory by integrating landmark infor mation into early cognitive mapping. Landmarks are used for encoding spatial relations within local spaces. A local matching method by using landmarks is proposed for recognition of revisited local spaces. Acquisition of more detailed metric information within local spaces by using landmarks and improved ability in the recognition of revisited local spaces are also among the main improvements obtained by integrating landmarks into Yeap and Jefferies' cognitive maps.
