extends TweakedLearner

A Tweaked Learner, with an optimization of the precision vs. recall

Author:

Giora Unger A learner whose score was optimized according to an F_beta() function, for a given beta. This optimization is used to fine-tune the precision vs. recall for the underlying classification algorithm. Values of beta<1.0 favor precision over recall, while values of beta>1.0 favor recall over precision. beta=1.0 grants equal weight to both precision and recall. Note: - Currently, in a hard-coded manner, the leaner takes a NaiveBayse class as its inner learner and a value of beta=1.0
