Definitions
- the invention relates to a prediction method and system, in particular to a prediction method and system for credit card user default based on BP_Adaboost model.
- the credit card default risk is driven by a potential payment failure when the cardholder makes a partial or full payment commitment, which occurs when the cardholder is in a tight or unwilling repayment period during the repayment period.
- risk management is downstream and risk prediction is upstream.
- the main purpose of risk forecasting is to use the performance of enterprises or the credit risk of individual customers to reduce risks and uncertainties, so it has great practical significance and value.
- data mining mainly studies and analyzes very large data, and uses automatic or semi-automatic programs to find previously unknown, interesting and understandable implicit information.
- banks can easily deploy a predictive model to quickly and efficiently analyze the default status of a large number of credit card holders, which has become an important tool for credit card analysis.
- discriminant analysis In order to reduce the influence of subjective factors in credit evaluation and reflect the dynamic changes of credit, discriminant analysis, logistic regression, classification tree and neural network method are gradually applied to the field of credit evaluation to predict the default behavior of credit card users.
- Discriminant analysis also known as the resolution method, is a multivariate statistical analysis method that discriminates its type attribution problem according to various eigenvalues of a certain research object under the condition of classification and determination.
- the basic principle of discriminant analysis is to establish one or more discriminant functions according to certain discriminant criteria, determine the undetermined coefficients in the discriminant function with a large amount of data of the research object, and calculate the discriminant index, according to which a customer sample can be predicted to belong to “ Good, the customer is still a default user.
- Logistic regression can be seen as a special case of linear regression models. This method can generate a simple classification probability formula to judge the probability that the sample belongs to each category, but its disadvantage is that it can not deal with nonlinear problems well and interpret the interaction between variables.
- CTs Classification Trees
- the credit card default prediction model established by this method does not generate a linear score table.
- the basic idea is to follow the value of a certain characteristic variable.
- the whole process can be represented by a tree structure, which is divided into "good” customers or "default” customers according to certain rules.
- BP Back Propagation neural network
- the BP network was proposed by a group of scientists led by Rinehart and McClelland in 1986. It is a multi-layer feedforward network trained by error inverse propagation algorithm. It has powerful parallel processing mechanism, high self-learning and self-adaptive ability.
- the BP neural network algorithm is very flexible because many of its internal parameters are adjustable.
- the main design idea of the BP neural network algorithm is: first, the input signal is calculated by the processing of the hidden layer and the output layer node, and the actual output of the network is obtained, and then compared with the expected output, and the error between the actual output and the expected output is calculated. The error is then propagated back to the input layer as a basis for modifying the weight. In this process, the output layer, the weight of the hidden layer, the threshold gain are calculated, and the weight and threshold are updated, and the process is repeated until the error between the actual output and the expected output reaches a preset error convergence criterion or reaches the highest iteration. The number of times, in order to obtain the final network weight, build a credit card default prediction model, and predict the sample.
- the above method can achieve a certain accuracy rate in credit card default prediction, but ignores the imbalance of credit card data, that is, the difference between the sample of the default customer and the sample number of the honest customer is too large.
- Boosting is a method to improve the accuracy of any given learning algorithm. Its idea originates from the PAC (Probably Approximately Correct) learning model proposed by Valiant. In 1995, Freund and Schapire improved the Boosting algorithm and proposed the AdaBoost (Adaptive Boosting) algorithm.
- the core idea of the Adaboost algorithm is to train different classifiers (weak classifiers) for the same training set, and then combine these weak classifiers. To form a stronger final classifier (strong classifier). Therefore, the Adaboost algorithm is robust to unbalanced data sets, and can enhance the classification effect and further improve the generalization ability of neural networks.
- the efficiency of this algorithm is almost the same as the Boosting algorithm proposed by Freund in 1991, but does not require any prior knowledge about weak learners, so it is easier to apply to practical problems.
- the same classification algorithm can be used when generating a single base classifier, and different classification algorithms can be used. These algorithms are generally unstable weak classification algorithms, such as the BP algorithm.
