WebFOIL is one of the simple and effective method for rule pruning. For a given rule R, FOIL_Prune = pos - neg / pos + neg. where pos and neg is the number of positive tuples covered by R, respectively. Note − This value will increase with the accuracy of R on the pruning set. Hence, if the FOIL_Prune value is higher for the pruned version of R ... WebClassification.
