Abstract
Methods, systems, and computer program products perform classification based on an imbalanced dataset. In a method, machine learning models are generated based on positive samples included in an imbalanced dataset. An amount of the positive samples is less than an amount of negative samples that are included in the imbalanced dataset. Each sample in the positive and negative samples includes parameters. Multiple influential parameter groups are identified from the parameters for the positive samples, respectively. A final predictive model is determined based on the machine learning models and the multiple influential parameter groups. The final predictive model is used for classifying a sample as a positive type or a negative type.
