Embodiment Construction
[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] The federated learning architecture proposed by the present invention is as follows: figure 1 As shown in the figure, serialization modeling is performed using reinforcement learning under the condition that user data and information are not available locally. During the process of communication between the local and the central server, the transmitted content is no longer the original data, but the model parameters of a certain proportion of the client. It solves the problem of data privacy protection and the low efficiency of centralized sampling, reduces the economic loss caused by cold start, and is of great significance for large-scale recommendation scenarios.
[0026] like figure 2 As shown, the sequence recommendation method based on federated learning mainly includes the following steps:
[0027] Step 1: The central server pr...
