Abstract

The embodiment of the invention provides a model generation method and device and a device for model generation. The method comprises: in response to a model generation request sent by a model demand side, obtaining ciphertext training data which is provided by at least two data providers and comprises user features of a sample user under a preset dimension and a user tag of the sample user; for the user features of any preset dimension, carrying out vector coding on the group numbers of the groups to which the user features belong, so as to obtain a vectorized training data matrix. and based on the training data matrix and the user tag, training to obtain a target model of the ciphertext, matching the processing mode of the ciphertext calculation party on the ciphertext with the encryption mode of the ciphertext training data, and returning the target model of the ciphertext to the model demand party. Therefore, by using the ciphertext training data of multiple data sources for training, the model training effect can be ensured to a certain extent, and the data security when multiple training data provided by multiple data providers are used for training is ensured.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a model generation method, device and device for model generation. Background technique [0002] In the process of model training, training data plays a vital role in the training effect of model training. [0003] In the existing method, when training the model, the data of a single data source is often used to directly train and acquire the model. In this way, the processing effect of the obtained model is often poor. Contents of the invention [0004] Embodiments of the present invention provide a model generation method, device and device for model generation, which can solve the problem that the processing effect of the model obtained through training is often poor. [0005] In order to solve the above problems, an embodiment of the present invention discloses a method for generating a model, which is applied to a ciphertext calculation party, and the method inc...
