Cluster analysis may be performed when one wishes to group similar objects into a given number of clusters. Several algorithms are available in order to construct these clusters. In this talk, focus will be on the generalized k-means algorithm which has the classical k-means procedure as well as the k-medoids algorithm as particular cases. Among the outputs of these clustering techniques, a cla...

Learning from imbalanced data is one of the greatest challenging problems in binary classification, and this problem has gained more importance recent years. When class distribution imbalanced, classical machine learning algorithms tend to move strongly towards majority disregard minority. Therefore, accuracy may be high, but model cannot recognize instances minority classify them, leading many...
