an epoch refers to finding and fixing the weight of a single node. We also tried the randomized search algorithm for a few real-world machine learning problems: lenses Hayes-Roth and the iris datasets [19]. The lenses data set is a data set that tries to predict whether people will need soft contact lenses, hard contact lenses or no contacts. The iris dataset details features of three different

on the level of cells, where a single cell may be generated by a different model than cells of the corresponding attribute for the other records from this class. 5 Evaluation 5.1 Naturally Corrupted Data Sets As an initial test, we ran LENS on several real world data sets. These data sets contained "natural" corruptions that were not explicitly generated from the assumed models. 5.1.1 Leaf and Rock Data

from old ones. Our discussion focuses on forward change mining, but it is equally applicable to backward change mining with the roles of old and new rules exchanged. Example 3.1. We use the Lenses data set from the UCI repository [14] to illustrate our approach. There are four attributes, three classes, and 18 examples: Attributes: A 1 : Age: 1, 2, 3 A 2 : Spectacle Prescription: 1, 2 A 3 :

More specifically, we used the lenses dataset containing 24 examples/patterns of 9 component values and the tictac-toe dataset containing 958 examples/patterns of 27 component values. Additionally, we used three datasets of ours produced from a

attributes. To explore the behavior of resampling estimators for non-numeric attributes in other inference environments, a series of experiments was conducted using the contact lens prescription data set [42]. In this artificial problem, patients are classified into 3 categories (hard, soft, none) based on the values of 4 attributes (1 tertiary and 3 binary). The 24 instances given cover all cases

To test the plausibility of this explanation, OPUS o was run again on the Lenses data set with Step 8 altered to ensure that where two siblings have equal optimistic value they are ordered in the same order as was employed with no optimistic reordering. This resulted in the exploration

These descriptions are classified into three classes according to the suitability of different types of contact lens The documentation for the data set indicates that a correct description of the target function requires 9 production rules. The distribution of the classification values is highly skewed, giving a relative frequency for the majority
