Shashank Bhatia and Stephan Chalup: A Model of Heteroassociative Memory: Deciphering Surprising Features and Locations. In: Computational Creativity 2013 ICCC 2013, 139-146.



The identification of surprising or interesting locations in an environment is an important problem in the fields of robotics (localisation, mapping and exploration), ar- chitecture (wayfinding, design), navigation (landmark identification) and computational creativity. Despite this familiarity, existing studies are known to rely ei- ther on human studies (in architecture and navigation) or complex feature intensive methods (in robotics) to evaluate surprise. In this paper, we propose a novel het- eroassociative memory architecture that remembers in- put patterns along with features associated with them. The model mimics human memory by comparing and associating new patterns with existing patterns and fea- tures, and provides an account of surprise experienced. The application of the proposed memory architecture is demonstrated by identifying monotonous and surprising locations present in a Google Sketchup model of an en- vironment. An inter-disciplinary approach combining the proposed memory model and isovists (from archi- tecture) is used to perceive and remember the structure of different locations of the model environment. The experimental results reported describe the behaviour of the proposed surprise identification technique, and illus- trate the universal applicability of the method. Finally, we also describe how the memory model can be modi- fied to mimic forgetfulness.
