Internet Financial Credit Scoring Models Based on Deep Forest and Resampling Methods

چکیده

In recent years, deep learning credit scoring models have become a hot research topic in Internet finance. However, most of the existing studies are based on neural network models, whose structure is difficult to design. Moreover, previous seldom considers impact class imbalance problems performance. To fill this gap, we propose new model forest (DF) and resampling methods. First, combine DF with five methods including random over-sampling (ROS), under-sampling (RUS), synthetic minority technique (SMOTE), tomek links SMOTE+ Tomek, respectively, build responding models. We validate that RUS-DF has best performance among above Then, further evaluate advantages ensemble RUS–DF, compare it four building by combining RUS multilayer perceptron, convolutional network, long short-term memory forests, respectively. All experiments conducted financial datasets. The results show obtains better classification stability than other suitable for solving problem imbalanced data.

Credit Risk Scoring Models

Credit scoring models play a fundamental role in the risk management practice at most banks. They are used to quantify credit risk at counterparty or transaction level in the different phases of the credit cycle (e.g. application, behavioural, collection models). The credit score empowers users to make quick decisions or even to automate decisions and this is extremely desirable when banks are ...

Two credit scoring models based on dual strategy ensemble trees

Decision tree (DT) is one of the most popular classification algorithms in data mining and machine learning. However, the performance of DT based credit scoring model is often relatively poorer than other techniques. This is mainly due to two reasons: DT is easily affected by (1) the noise data and (2) the redundant attributes of data under the circumstance of credit scoring. In this study, we ...

Credit Scoring Models with AUC Maximization Based on Weighted SVM

Credit scoring models are very important tools for financial institutions to make credit granting decisions. In the last few decades, many quantitative methods have been used for the development of credit scoring models with focus on maximizing classification accuracy. This paper proposes the credit scoring models with the area under receiver operating characteristics curve (AUC) maximization b...

Credit Scoring using Semiparametric Methods

Credit scoring methods aim to assess credit worthiness of potential borrowers to keep the risk of credit loss low and to minimize the costs of failure over risk groups. Standard parametric approaches as logistic discrimination analysis assume that the probability of belonging to the group of ”bad” clients is given by P (Y = 1|X) = F (βX), with Y = 1 indicating a ”bad” client and X denoting the ...
