METHOD AND APPARATUS FOR ENCRYPTING DATA, METHOD AND APPARATUS FOR TRAINING MACHINE LEARNING MODEL, AND ELECTRONIC DEVICE

摘要

A method for encrypting data is disclosed, and includes the following: generating an N×M dimensional target matrix based on N data samples and M dimensional data features respectively corresponding to the N data samples; performing encryption calculation on the target matrix based on a PCA algorithm to obtain an encrypted N×K dimensional encryption matrix; and transmitting the encryption matrix to a modeling server, so that the modeling server trains a machine learning model by using the encryption matrix as a training sample.
