Data analysis apparatus |
摘要 |
To analyze symbolized time series data in units of a case and extract a causal relation included in the data as a rule representing a data structure, time series data are stored as records of a symbol and a time by a symbolized data management apparatus, and a unit of description of an analysis is determined by a case production apparatus and a classification apparatus. A model extraction apparatus extracts a data structure included in a class by case and outputs the extracted data structure as a rule. Analysis results are output as a temporal relationship between a case and a rule, indicating a conformity degree between cases, by the symbolized data management apparatus. |
