Embodiment Construction

[0045] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0046] Currently, feature processing for different nodes (such as decomposition of multiple organizations by non-negative matrix decomposition techniques), typically requires features of these nodes to achieve the above-described decomposition process. This cannot guarantee data security between different nodes.

[0047] To this end, the present application provides a feature processing method to be treated in the process of processing the features of the different nodes, and all sub-features before the processing before the nodes are not known. The security of data between nodes.

[0048] First, the application scenario of the present application embodiment will be described. The feature processing method provided herein can be applied to data processing devices such as terminal devices, servers. Terminal devices can be, for example, a smart terminal, a compute...

Abstract

The embodiment of the present application discloses a feature processing method and related equipment. After obtaining the user IDs corresponding to the original features sent by different nodes, the same user ID set can be determined according to the user IDs, and the same user ID set can be sent to different nodes. If it is in the first feature processing mode and receives the first sub-features obtained by each node after the i-th round of feature processing for the features to be processed, the first sub-features can be aligned to generate the i+1-th round of feature processing First synchronize subfeatures and send them to different nodes. Among them, the feature to be processed is the feature corresponding to all users in the same user identification set determined by each node from the original feature. Since the method does not obtain the original features, features to be processed, and all sub-features after processing of each node from the beginning to the end, the security of data between different nodes is guaranteed.

Description

Technical field [0001] The present application relates to the field of data processing, and in particular to a feature processing method and related device. Background technique [0002] In a feature processing mode, the feature of different nodes is required to be two or more sub-features, while also ensuring that different nodes are the same for one of the sub-features obtained after the feature decomposition. For example: multiple organizations (nodes) have some data (features) for common users or common products, requiring non-negative matrix decomposition methods to study user portraits or product portraits of these organizations to be recommended. Alternatively, multiple hospitals (corresponding nodes) have different patient diagnostic data on the same disease, and these hospitals need to be studied together, and the non-negative matrix decomposition method can be used to decompose. [0003] For security, there is no desire to infer its own characteristics between different...
