This invention belongs to the field of credit. It is a classification model for the default risk of credit customer based on deep learning. The invention consists of the following steps: Firstly, we collect real data, fill in missing values, and, therefore, obtain relatively complete and valuable data. Secondly, the preprocessed data set is divided into training set and test set. Thirdly, we use one hybrid unsupervised and supervised method to analyze the training set data. After determining the model, we used grid search to adjust parameters, such as learning rate and depth, to get the optimal performance model. Finally, we use trained model to examine the test set in order to effectively predict the default risk of customers.
