| Abstract(in English) | Hyper-Column Model (HCM) is a self-organized, competitive and hierarchical multilayer neural network. It is derived from the Neocognitron by replacing each S cell and C cell with a two layer Hierarchical Self-Organizing Map (HSOM). HCM can recognize images with variant object size, position, orientation and spatial resolution. Original HCM has connections only with its input layer or bottom layer and does not assume lateral connections among HSOMs. In this paper, we propose a new learning method with excitatory lateral connections. HCM can learn patterns of winner neurons which are activated in each HSOM by updating the excitatory connections, which improves the recognition accuracy. In recognition phase, HCM imposes constraints on the neurons which are activated in each HSOM by using the excitatory connections. We call this learning method "Sparse Code Learning" from the viewpoint that an entire activation pattern is described as multiple neurons. |
