DecomposableDynamicPartialRuleEvaluationFactory(float32 threshold, float32 exponent, float32 l1RegularizationWeight, float32 l2RegularizationWeight)¶

Parameters:

threshold – A threshold that affects for how many outputs the rule heads should predict. A smaller threshold results in less outputs being selected. A greater threshold results in more outputs being selected. E.g., a threshold of 0.2 means that a rule will only predict for an output if the estimated predictive quality q for this particular output satisfies the inequality q^exponent > q_best^exponent * (1 - 0.2), where q_best is the best quality among all outputs. Must be in (0, 1)
exponent – An exponent that should be used to weigh the estimated predictive quality for individual outputs. E.g., an exponent of 2 means that the estimated predictive quality q for a particular output is weighed as q^2. Must be at least 1
l1RegularizationWeight – The weight of the L1 regularization that is applied for calculating the scores to be predicted by rules
l2RegularizationWeight – The weight of the L2 regularization that is applied for calculating the scores to be predicted by rules
