English

Subject field(s)
  • Artificial Intelligence
DEF

A numerical weight given to a fact or relationship to indicate the confidence one has in the fact or relationship. These numbers behave differently than probability coefficients. Most rule-based systems use certainty factors rather than probabilities.

CONT

The number 800 appearing in the action of the sample rule is called a certainty factor. It indicates on a scale from - 1 to 1000 how certain the conclusion is, given that the premise is known to be true with certainty.

OBS

certainty factor, confidence factor: terms standardized by ISO/IEC and CSA.

French

Domaine(s)
  • Intelligence artificielle
