Predicting the number of defects in software modules can be more helpful in the case of limited testing resources. The highly imbalanced distribution of the target variable values (i.e., the number of defects) degrades the performance of models for predicting the number of defects. As the first effort of an in-depth study, this paper explores the potential of using resampling techniques and ensemble...
Groundwater level has random characters because of influences factors of natural and anthropogenic. Study random prediction model of groundwater level on the basis of groundwater physical process analysis is important to groundwater appraisal. The theory of supporting vector machine based on small-sample machine learning theory is introduced into dynamic prediction of groundwater level. A least square...
