| Outline of Final Research Achievements |
The models in neural networks have aimed to create representations faithful to input patterns as much as possible. However, it has turned out that the faithful representations are not necessarily effective in actual situations. Thus, the present study attempted to create multiple representations, depending on different situations. However, in the course of this pursuit to the open representations, it has turned out that it is necessary to build up more powerful network models for realizing open representations. For this, new multi-layered neural networks model was developed based on the information-theoretic self-organizing maps. In addition, the definition of information content should be changed to take into account the possibility of the information more exactly. Finally, the information theoretic methods should be simplified to be applicable to large data sets.
