Unsupervised Grounding of Spatial Relations
Original language description
We present an unsupervised connectionist model for grounding color, shape and spatial relations of two objects in 2D space. The model constitutes a two-layer architecture that integrates information from visual and auditory inputs. The images are presented as the visual inputs to an artificial retina and five-word sentences describing them (e.g.~``Red box above green circle'') serve as auditory inputs with phonological encoding. The visual scene is represented by the Self-Organizing Map(s) and the auditory description is processed by a recursive SOM (RecSOM) that learns to topographically represent sequences. Primary representations are integrated in a multimodal module (implemented by SOM or Neural Gas algorithms) in the second layer using self-organizing units with conjunctive representations. We tested this two-layer architecture in two versions (a single SOM representing color, shape and spatial relations vs. biologically inspired separate SOMs for spatial relations and for shape a
