Abstract: The embodiments are directed towards providing personalized federated learning (PFL) models via sharable federated basis models. A model architecture and learning algorithm for PFL models is disclosed. The embodiments learn a set of basis models, which can be combined layer by layer to form a personalized model for each client using specifically learned combination coefficients. The set of basis models are shared with each client of a set of the clients. Thus, the set of basis models is common to each client of the set of clients. However, each client may generate a unique PFL based on their specifically learned combination coefficients. The unique combination of coefficients for each client may be encoded in a separate personalized vector for each of the clients.

Abstract: Disclosed is a catalytic promoter for fluid catalytic cracking of hydrocarbons, comprising a HZSM-5 zeolite in an amount of 5-65 wt % based on the total weight of the catalytic promoter, said zeolite being modified with Zn and at least one element selected from the group consisting of P, Ga, Al, Ni and rare earth elements, the combined amount of said modifying elements being 0.01-10.37 wt % based on total weight of said modified HZSM-5 zeolite. A reduced olefin content in gasoline from catalytic cracking process, an increased gasoline octane number and an increased lower olefin yield can be obtained using said catalytic promoter.
