Smart Grid is an intelligent power grid with a bidirectional flow of electricity and information, that applies techniques to operate the autonomously near stability limit. An technique developed identify predict abnormalities due changes in customer behaviour unexpected disruption grid. A cost-sensitive stacked ensemble classifier (CS-SEC) proposed for predicting operations smart combines four ...

The classification of data with imbalanced class distributions has posed a significant drawback in the performance attainable by most well-developed classification systems, which assume relatively balanced class distributions. This problem is especially crucial in many application domains, such as medical diagnosis, fraud detection, network intrusion, etc., which are of great importance in mach...

Multi-label data classification has become an important and active research topic, where the classification algorithm is required to deal with prediction of sets of label indicators for instances simultaneously. Label powerset (LP) method reduces the multi-label classification problem to a single-label multi-class classification problem by treating each distinct combination of labels. However, ...
