  • Publication number: 20230394295
    Abstract: Aspects of the present disclosure relate to a providing related content recommendations in response to a user search query by supervising the training of pair embeddings using contrastive learning and pairwise co-click signals. The approach combines a two tower model architecture with a cascaded multilayer perceptron model to enable the adoption of variable combinations of input features and more representative learned pair embeddings. The learned embeddings undergo supervised contrastive loss training to generate a related content recommendation model, which is subsequently evaluated using both online and offline metrics. The related content recommendation model can provide results to search queries that improve recommendation quality and increase user engagement, thereby ultimately enhancing long term user experience.

  • Publication number: 20230395743
    Abstract: Provided is a preparation method of a detector material. The present disclosure epitaxially grows a buffer layer on a surface of a gallium arsenide substrate, deposits a silicon dioxide layer on the buffer layer, and etches the silicon dioxide layer on the buffer layer according to a strip pattern by photolithography and etching to form strip growth regions with continuous changes in width. Finally, a molecular beam epitaxy (MBE) technology is used to epitaxially grow the detector material in the strip growth regions under set epitaxy growth conditions. Because of the same mobility of atoms arriving at the surface of the substrate, numbers of atoms migrating to the strip growth regions are different due to different widths of the strip growth regions, such that compositions of the material change with the widths of the strip growth regions or a layer thickness changes with the widths of the strip growth regions.

    Abstract: The present disclosure provides a method for preparing multi-component polymers through post-polymerization modification, used to functionalize polysulfonyl imidate polymer including a dispersing polymer reactant, an electrophilic substitution reagent and a catalyst in an organic dispersant; adding acid-binding agent to react at room temperature for 4-48 h; obtaining the precipitate when the reaction finished; washing and drying the obtained precipitate to get the functionalized multi-component polymers. The present disclosure involves a low polymerization temperature, allowing for the reaction to occur at room temperature. Additionally, the conversion rate is high, and the applicable electrophilic substitution monomer reagents have a wide selection. Besides that, the synthesis cost of the reaction is low due to the widespread availability of common chemical reagents such as catalysts, organic dispersants, acid binding agents, and other reaction reagents.
