Abstract

The invention provides a data processing method and device, equipment and a storage medium, relates to the technical field of data processing, in particular to big data, artificial intelligence and block chain technologies, and can be used for cloud computing and cloud services. The specific implementation scheme is executed by any node in multiple nodes, and comprises the following steps: determining a target statistical value according to a deviation secret of an initial statistical value of first sample data of a local node and obtained deviation secrets of initial statistical values of respective second sample data of other nodes in the multiple nodes; and performing standardization processing on the first sample data according to the target statistical value, wherein the target statistical value comprises at least one of a feature total mean value, a feature total variance and a feature total standard deviation of all sample data of the multiple nodes under a predetermined feature dimension. According to the technical scheme disclosed by the invention, each node in the multiple nodes performs unified standardization on respective sample data, and meanwhile, leakage of data privacy of each node caused by direct initial statistical value interaction is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, especially big data, artificial intelligence and block chain technology, which can be used for cloud computing and cloud services. Background technique [0002] With the development of artificial intelligence technology, machine learning has been more and more widely used in various scenarios. In machine learning solutions, before starting to train the model, it is usually necessary to standardize the sample set to eliminate dimensionality and speed up model convergence. [0003] In distributed machine learning, multiple participants need to share sample data to achieve uniform standardization of sample data from all parties. However, the above method has brought hidden dangers to the data security of each participant. Contents of the invention [0004] The present disclosure provides a unified and standardized data processing method, device, device, and storage medium for mu...
