Fuzzy inference label standardization device and fuzzy inference device

摘要

PURPOSE:To easily determine which membership function is to be made common on a fuzzy inference device which derives a conclusion from vague and uncertain information and knowledge. CONSTITUTION:A function shape feature value extraction part 1 extracts the shape of the membership function as feature values and function shape feature values of plural parts featuring the shape of the membership function. A clustering part 2 performs clustering by the feature parts as to all membership functions on the basis of the function shape feature values. An identical membership function detection part 3 detects a group of membership functions belonging to the same cluster as to all kinds of function shape feature values. A common membership function generation part 4 makes membership functions in the same group detected by the identical membership function detection part common between rules and input variables.
