In this paper, we develop a new multilayer neural model that forms categories of inputs for some practical applications such as pattern recognition, learning, image processing, and trend analysis. An essential core of the model is to use a novel vector representation of concepts that compose an input in a multi-level informational hierarchy that makes the model possess category formation ability from incomplete observation of the input. Simulation results demonstrate the usefulness of the model for a facial image recognition task, even if it is carried out under an incremental and unsupervised learning environment. In addition, we evaluate the adequacy and efficiency of formed categories by using principal component analysis.
