Fuzzy backward reasoning device

摘要

A sequential type Fuzzy backward reasoning device is disclosed, which is capable of performing computation progressing every time a feature quantity is observed to update reasoning and of performing the reasoning even if the order of observations is arbitrary, by providing means for performing sequential reasoning instead of batch type reasoning means, and feedback means for feeding back a reasoned result. Additionally, a target recognition device is disclosed which is capable of computing as a numerical value the reliable degree of a recognized result on a target by obtaining another recognizing information even if there is not obtained any information concerning the target, using said sequential type Fuzzy backward reasoning device.
