Embodiment Construction
[0030] The embodiment of this application aims to solve the problem of how to achieve the goal of model training, especially the completion of longitudinal federated logistic regression learning under the premise of ensuring that the data set is not leaked, and at the same time, it can also be well adapted to the application scenarios of federated learning or similar privacy computing. A heterogeneous acceleration method, device and system are provided for this technical problem due to the demand for storage resources and computing performance brought about by large integer bit width data and dense state operations. The method includes: the first participant and the second participant perform plaintext operations and encryption operations according to their respective characteristic data to obtain the encrypted model parameters of the first participant and the encrypted model parameters of the second participant respectively, wherein the The feature data is the data in the mini...
