+The numbers next to each of the attributes values marked as ''cf'' are certainty factors assigned to each values representing the confidence in the value. Some CF's are less than one, as we explicitly set that the confidence of the rules producing these values are lower (see last column of each table, with ''#'' in the header). For more on how to use certainty factors to handle uncertainty see [[pub:software:heartdroid:tutorials:uncertainty_cf|Managing uncertainty with Certainty Factors Algebra]] tutorial.
