Interface for expert system - contains threshold value adjustment and probability threshold comparison arrangements enabling conclusion verification

摘要

The interface for an expert system contains an arrangement for adjusting an threshold value for each conclusion, an arrangement for compating the probability of a conclusion and a corresp. threshold and to output a conclusion with a probability greater than or equal to the threshold. A false information input device is used to enter invald information with a conclusion with a probability greater than or equal to the threshold or valid information with a probability less than the threshold. The threshold is adjusted to eliminate errors. ADVANTAGE - Enables probability of each conclusion to be determined and its validity verified.
