Assign cases into one of several categories, such as high-, medium-, and low-risk groups. The “stratification” causes the training set and the test set to have the same 70/30 distribution of good and bad credit samples, so that a sample test set will contain 60 bad credit samples chosen from in the set overall. Evaluate the obtained clusterings by comparing them to the original set of topics or to the topic hierarchy (when using Cobweb). Dr.

Exploration of Weka predictions from the baseline dataset showed that a major source of con-fusion for the machine learning algorithms was an inability to distinguish between pairs of drugs that do and do not interact within the same sentence. The WEKA visual level indicator is ideal for the commissioning of systems. Assign cases into one of several categories, such as high-, medium-, and low-risk groups. The Experimenter does something very slightly different to reduce variance in the estimates if the class attribute is nominal by implementing stratification: weka stratification manually after shuffling, approximately 66% of the data for *each class* is taken and the union of these per-class subsets is used as the training set. Then later, we’ll make it think spring has come. A third is to apply several different learners and compare their performance in order to choose one for prediction.
