Embodiment 1

[0046] This embodiment provides a joint modeling method, aiming to protect the data security of the business party while implementing joint modeling. Specifically: the modeling party provides behavioral sample data to increase the data dimension of modeling, and the modeling party sends the provided behavioral sample data to the business party for feature selection, and groups the behavioral sample data based on the selected behavioral characteristics, so that there is Users with the same characteristics are grouped into the same group, and the matching rate and the proportion of positive samples between the business sample and the modeler sample are calculated in the form of user groups, so that the modeler can group the behavior sample data according to the same grouping rules. The whole modeling process does not directly involve the processing of specific user information, and the business party does not need to provide the modeling party with its own user preference data, w...

Embodiment 2

[0092] The difference between this embodiment and Embodiment 1 is that the processing result of the behavior sample data set is received, and the processing result includes: grouping rules, and several data obtained by grouping the behavior sample data sets according to the grouping rules. User groups and the matching rate and positive sample ratio of each user group obtained by comparing user preference sample data sets;

[0093] Mark each user group according to the matching rate and positive sample proportion of each user group, and perform modeling according to the marked user group.

[0094] This embodiment achieves the same technical effect as Embodiment 1, except that the processing results of the transmission are different. In this embodiment, the user groups obtained through the grouping process according to the grouping rules are also transmitted as the processing results, so that the modeling party receives the processed After the results, there is no need to perfor...

Embodiment 3

[0096] image 3 A schematic structural diagram of an electronic device provided by Embodiment 3 of the present invention, such as image 3 As shown, the electronic device includes a processor 210, a memory 220, an input device 230, and an output device 240; the number of processors 210 in a computer device may be one or more, image 3 Take a processor 210 as an example; the processor 210, the memory 220, the input device 230 and the output device 240 in the electronic device can be connected through a bus or other methods, image 3 Take connection via bus as an example.

[0097] The memory 220 is a computer-readable storage medium and can be used to store software programs, computer-executable programs and modules, such as program instructions / modules corresponding to the joint modeling method in the embodiment of the present invention. The processor 210 executes various functional applications and data processing of the electronic device by running software programs, instru...

Abstract

The invention discloses a joint modeling method, relates to the field of data processing, aims to carry out joint modeling on the premise of ensuring data security of all parties, reduce leakage riskof sensitive data while the data dimension is increased; the method comprises the following steps that: a modeling party sends a desensitized behavior sample data set to a service party, the service party groups the behavior sample data set according to a grouping rule to obtain a plurality of user groups, and compares preference samples of the service party with behavior samples in the user groups to obtain matching rates and positive sample proportions of the user groups; and the modeling party processes the desensitized behavior sample data set according to the same grouping rule and the matching rate and the positive sample proportion of each user returned by the service party, and performs modeling according to the processed data. The invention further discloses electronic equipment and a computer storage medium.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a joint modeling method, device and medium. Background technique [0002] In data modeling, due to incomplete customer group information dimensions or insufficient modeling capabilities of the business side, it is usually necessary to combine other parties' data dimensions for modeling. For example, based on the joint modeling of banks, banks mainly use the central bank's credit information, user records, etc. as data sources, and lack user behavior data from other industries, so they usually need to combine third-party data for modeling. [0003] In the traditional joint modeling scenario, the business party generally provides samples containing actual data, and then the modeling party completes the modeling based on the samples, that is: 1) The business party selects the sample data and directly provides the sample data details to experts Modeling team; 2) The expert modeling te...
