Abstract:
The present invention relates to a method for supplementing class-imbalanced data, and a method for predicting a loan default using same, the method for supplementing class-imbalanced data comprising the steps of: receiving, as an input, class-imbalanced data having an imbalance between the number of minority class data and the number of majority class data; extracting the minority class data from the input data; learning, through a balancing GAN, the extracted data so as to generate data; and adding the generated data to the input data so as to supplement the data.
