- feature extraction is a feature vector calculated by performing statistics on the behavior of the performance data.
- a matrix is constructed with fulfillment data as row vectors, behavior features as column vectors, and fulfillment scenarios as classification values.
- the performance scenario is the embodiment of credit service, that is, a specific service provided by a service provider, such as merchant A, XX free deposit borrowing umbrella.
- the user's credit rating is at least one dimension that affects the type of credit service.
- User characteristics and third-party feedback characteristics can be two determinants of credit rating.
- User characteristics may include: user credit score, user education, and user age.
- the characteristics of third-party feedback can include: whether there is negative information about court arbitration and whether there is a bank breach of contract. For example, the data "user A, 666 points, undergraduate and 32 years old, none" can indicate that user A's credit score is 666 points, the highest degree is undergraduate, the age is 32, and there is no breach of credit in the credit investigation.
- the user’s performance behavior habits are another dimension that affects the type of credit service.
- the user’s performance behavior habits can be mined based on the user’s credit performance data, such as performance characteristics and amount categories. feature.
- Performance characteristics can include: number/month, whether there is a financial scenario, whether there is a default, and the number of performance scenarios.
- Amount characteristics can include: performance amount/time, discount amount/time. For example, the data "User C, 16 times/month, financial scenario, no default, 5" indicates that user C has performed 16 times in the month, which is a financial scenario with no default behavior, and there are 5 performance scenarios.
- the characteristics of the service provider are also a dimension that affects the type of credit service.
- the characteristics of the service provider may include: the total number of services, the total number of services, and the performance rate.
- Rule features can include: service discounts, service access points.
- the total number of services can indicate how many users the service provider has provided services to.
- the total number of service visits can indicate how many times the service provider has provided users with services in total.
- the fulfillment rate can indicate the probability that users who use the service provided by the service provider will successfully fulfill the contract.
- Service discount can indicate the degree of preferential service provided by the service provider. Such as a 20% discount.
- the service access score indicates the access threshold for users of the credit service provided by the service provider.
- users with a credit score of 600 can use the credit service provided by the service provider.
- “Merchant B, deposit-free lease, 237, 931, 95%, and 650” can indicate that the total number of people served by Merchant B is 237, the total number of services is 931, the user's performance rate is 95%, and the service access It is divided into 650 credit points. From the above data, it can be inferred that the user will use the service provided by merchant B many times, and the user's fulfillment rate is very high.
- the main process of the random forest algorithm is as follows:
- Decision tree A tree structure model induced by top-down recursion of data instances and based on the difference in information entropy. Using the top-down recursive method, the basic idea is to construct a tree with the fastest decrease in entropy value as a measure of information entropy, and the entropy value at the leaf node is 0, that is, the instances of leaf nodes are classified into one category.
- Random forest uses the idea of ensemble learning to classify the itinerary model of multiple decision trees at the data training place. Ensemble learning is to train multiple classifiers, and finally integrate the classification results to determine the classification idea of the tuple category.
- the C4.5 algorithm is used as the decision tree algorithm, and the information gain rate is used as the feature split rule to train a set of decision trees.
- the C4.5 algorithm is a kind of decision tree algorithm.
- the decision tree can represent the classification process as a tree, and each time it bifurcates by selecting a feature pi.
- the selected K features may include multiple types of features, such as performance-based features, monetary-based features, user features, and third-party feedback features. It can also be multiple characteristics of the same type of characteristics, such as user characteristics: one or more of user credit score, user education, and user age.
- the random forest algorithm is adopted, and the method of integrated learning random + voting is used to enhance classification accuracy, resist noise and prevent overfitting, and can obtain high-precision classification accuracy and recall.
- a random forest algorithm is used to train the credit service classifier. Since the classification accuracy of a single decision tree has large deviations on different classification sets, overfitting may also occur on a single classification set. Overfitting means that the model performs well on the training set, but performs poorly on the test set. The reason is mostly that the selection of the training set is unreasonable. For example, the training set is basically all apples. Using this training set to classify fruits and vegetables, the training model performs particularly well, but the strawberry in the test set cannot be classified.
- Random forest draws on the idea of ensemble learning, uses sample set sampling, feature set selection, and classification algorithm selection to train different decision trees, and then uses principles such as majority voting to complete the aggregation of results, which can not only improve classification accuracy, but also Effectively avoid overfitting of a single classifier.

- the “try-first-credit-buy service” has higher requirements for the user's credit rating than the "credit-free service” has a higher requirement for the user's credit rating.
- different credit services can be provided for different user groups. For example, the service access of "Credit first try before buying service” is divided into 650, which means that users are required to have a credit score of 650 or more to enjoy this service, and the service access of "Credit Free Service” is divided into 600, which means the user's credit is required. You can enjoy this service with a score of 600 or more.
- the “try-first-credit-buy service” can be recommended for the user, and when the user's credit score is 610, the "credit-free service” can be recommended for the user.
- credit services can be further screened based on the user's performance characteristics.
