“…Hence the set pressure encourages the evolution of rules which cover many data points and the fitness pressure acts as a limit upon the separation of such data points, i.e., the error. Tammee et al [2006] began by using a slightly simplified version of XCS as the underlying LCS (YCS) [Bull, 2005], but found that XCS's relative accuracy fitness function was more effective than a function directly inversely proportional to error [Tammee et al, 2007]  is set high, e.g., 0.1, in less-separated data the contiguous clusters are covered by the same rules. They therefore developed an adaptive threshold parameter scheme which uses the average error of the current [M]:…”

“…Unsupervised learning describes those tasks under which structure is sought in unlabelled data without further external input. Perhaps somewhat surprisingly, no previous suggestion of the use of LCS for such learning is known in the literature until the work of Tammee et al [2006;2007] on clustering (see Figure 7). Clustering is an important unsupervised learning technique where a set of data are grouped into clusters in such a way that data in the same cluster are similar in some sense and data in different clusters are dissimilar in the same sense (see [Xu & Wunsch, 2009] for an overview).…”

“…Αξιόλογες είναι και οι θεωρητικές αναλύσεις [BP01, BKLW04, BGL05, BGLS07, DB08, Dru08] που οδήγησαν στην καλύτερη κατανόηση του συστήματος. Τέλος, ο XCS και παρόμοια συστήματα έχουν εφαρμοστεί σε σημαντικές εφαρμογές όπως η εξόρυξη γνώσης [Bul04,BBMH08], η προσέγγιση συναρτήσεων [Wil02a,BLW08], η ενισχυτική μάθηση [Lan99b, Lan02, LLWG05, BGL05], και η ομαδοποίηση [TBP06,TBP07], αναδεικνύοντας την ανταγωνιστικότητα των ΜαΣΤ, και ειδικότερα του XCS, σε σχέση με άλλες τεχνικές μηχανικής μάθησης που βασίζονται σε διαφορετικές προσεγγίσεις, όπως τα δέντρα απόφασης [Qui93] ή τα νευ-ΚΕΦΑΛΑΙΟ 1.

“…Παράλληλα με τις προαναφερθείσες εφαρμογές του XCS σε διάφορα πεδία, υπήρξαν και προσεγγίσεις στις οποίες η αρχιτεκτονική μάθησης του XCS τροποποιήθηκε για συγκεκριμένους τύπους προβλημάτων [Wil02a,BMGG03,Bul05,TBP06]. Συγκεκριμένα στην περίπτωση της κατηγοριοποίησης δεδομένων, οι Butz et al [BGT03] εντόπισαν ότι ο XCS παρήγαγε μία παραπλανητική πίεση προς τη βέλτιστη λύση σε συγκεκριμένα προβλήματα.…”
