Embodiment Construction

[0042] In order for those skilled in the art to better understand the technical solutions in the embodiments of this specification, the technical solutions in the embodiments of this specification will be described in detail below in conjunction with the drawings in the embodiments of this specification. Obviously, the described implementation Examples are only some of the embodiments in this specification, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this specification shall fall within the scope of protection.

[0043] Such as figure 1 As shown, in the cooperation mode of "data sharing", several roles are involved: data provider, data mining party, and data attacking party. Multiple data providers jointly hand over the data to the data mining party for data sharing and mining, but in order to protect data privacy, they do not want to provide the data intact to the data mining party. On the other hand, t...

Abstract

A model training method and apparatus based on shared data are disclosed. The scheme is used to train the data model according to the mass data sample, wherein the data samples are from multiple dataproviders, different data providers can provide data sample characteristics from different dimensions, the data samples with richer feature dimensions can be formed after the data shared by differentdata providers are integrated, so that a better data model can be trained and the security of data sharing can be ensured at the same time.

Description

technical field [0001] The embodiments of this specification relate to the technical field of data mining, and in particular to a model training method and device based on shared data. Background technique [0002] In the era of big data, various forms of useful information can be obtained by mining massive data, so the importance of data is self-evident. Different institutions have their own data, but the data mining effect of any institution will be limited by the amount and type of data it owns. Aiming at this problem, a direct solution is: multiple institutions cooperate with each other to share data, so as to achieve better data mining effect and achieve a win-win situation. [0003] However, for the data owner, the data itself is a valuable asset, and due to the need to protect privacy and prevent leakage, the data owner is often unwilling to provide the data directly. This situation leads to "data Sharing" is difficult to actually work in reality. Therefore, how to...
