  • Patent number: 12242552
    Abstract: A method, performed by at least one processor of a computing device, for recommending an event, the method including determining a frequency of execution of the event by a user among a plurality of users; determining an inverse user frequency of execution of the event based on the plurality of users who have executed the event; generating a recommendation factor by modifying the frequency of execution of the event by the user based on the inverse user frequency of execution of the event; and outputting a recommendation for the event based on the recommendation factor.

  • Publication number: 20250006902
    Abstract: An oxide composite positive electrode material coated with borate in situ, includes ?AxByOz—NaaLibNicCudMneMfO2+?. In the material, Li, Ni, Cu, Mn, and element M for doping and substituting a transition metal site together occupy the position of transition metal ions in the crystal structure. The space group of the layered oxide composite positive electrode material is P63/mmc or P63/mcm or R3m, or the corresponding structure is a P2 phase or an O3 phase. AxByOz is a coating layer that has a needle-like structure and is generated in situ on the surface of NaaLibNicCudMneMfO2+?, being formed by, during a sintering process, coating a material precursor and a layered oxide precursor for generating NaaLibNicCudMneMfO2+?; ? is the mass fraction of the coating material precursor in the layered oxide precursor, 0.1 wt %???10 wt %; and A is Li and/or Na.

  • Publication number: 20240242068
    Abstract: System, method, device, and program for graph embedding based on graph data and non-graph data are provided. The method and processes may be executed by at least one processor and may include receiving graph data associated with one or more users, and receiving classification data associated with the one or more users, wherein the classification data comprises non-graph data associated with the one or more users. The method and processed may further include generating an accuracy parameter based on the classification data associated with the one or more users, wherein the accuracy parameter indicates an accuracy of neural network-based classification results based on the classification data; and generating numerical node representation using a neural network-based graph embedding model associated with the one or more users based on the graph data, the classification data, and the accuracy parameter.
