Abstract

The invention provides a machine learning method, device and system of a distributed system, electronic equipment and a computer readable storage medium. An artificial intelligence technology is involved. The method comprises the following steps that: master equipment performs homomorphic encryption on a global gradient scalar of a machine learning model, and sends the obtained encrypted global gradient scalar to slave equipment; the slave equipment determines an encrypted local gradient corresponding to the slave equipment based on the encrypted global gradient scalar, feature data stored bythe slave equipment for the training sample and a local model parameter corresponding to the slave equipment; the master equipment and the slave equipment jointly decrypt the encrypted local gradientcorresponding to the slave equipment to obtain a decryption local gradient corresponding to the slave equipment; and the slave equipment updates a local model parameter corresponding to the slave equipment based on the decrypted local gradient corresponding to the slave equipment. According to the invention, the safety of the training data can be ensured.
