“…In case maximal size of the redescription set is reached, the algorithm exchanges the newly produced redescription with the worst incomplete candidate from R (lines 11 to 19 in Algorithm 1 [28]. In this work we use three models: a) The random forest of multi-target regression (multi-label classification) PCTs [18], b) The Random Forest of Extra randomized multi-target PCTs [17] and c) The Random Forest of multi-target regression PCTs with Random Output Selections [5] (see Section IV-D for motivation and more details).…”

“…The model M obtained using algorithm Alg is used to generate targets that connect two views and is transformed to rules used to create redescriptions (more detailed explanation can be seen in [26]). Rules obtained from a model M , obtained using Alg , are used to increase diversity and accuracy of produced redescriptions [28]. In this work, we only test Predictive Clustering trees and Extra multi-target PCTs (M) as models from which main rules are generated.…”

“…The RF is an ensemble learning algorithm [20] extended from DT algorithm and trained by the ensemble learning theory of bagging. In RF algorithm, once the tree classifier is established, each DT will receive a result about the class of a newly inputted user sample.…”

InterSet can also facilitate understanding of supervised problems (in particular multi-label predictive problems), if redescription mining is performed on input attributes and target attributes as two separate views.…”
