Outline of Final Research Achievements |
We developed "A Method of Knowledge Creation and Knowledge Utilization” by Generalized Inverse Operator" for Big Data, We established a model by regarding the Knowledge creating Operator and the Knowledge Utilization Operator as the inverse operator mutually. The main problem is the creating the inverse operator is not well-posed and we cannot construct the inverse operator properly, We need some auxiliary conditions and probabilistic process to the problem. We succeeded to make the problem well-posed by combining the auxiliary constrained conditions, notion of generalized inverses and probabilistic conditions. We applied this method to 3 different class of problems and sucessfully implemented the method to the system.
