  • OBJECT IDENTIFICATION BASED ON LONG-TERM USER BEHAVIOR AND SHORT-TERM INTEREST
    Publication number: 20220138213
    Abstract: The described implementations are operable to determine potential objects of interest to a user based on a blend of the user's long-term behavior and short-term interests. Long term user behavior may be determined for the user over a period of time and represented as continuous data. Short-term interest may be determined based on objects with which the user has recently interacted, and attributes of those objects may be represented together as continuous data corresponding to the short-term user interest. The continuous data of the short-term user interest and long-term user behavior may be blended to produce a user embedding. The user embedding may then be compared with objects to determine objects that are of potential interest to the user.

  • Circuit for increasing output direct-current level of transimpedance amplification stage in TIA
    Patent number: 11218124
    Abstract: A circuit for increasing an output direct-current level of a transimpedance amplification stage in a TIA (Trans-Impedance Amplifier) includes a transimpedance amplification stage, a differential amplification stage, a level boosting unit, and a DC-restore loop. An input terminal of the transimpedance amplification stage is used for inputting a photocurrent signal. An output terminal of the transimpedance amplification stage is directly connected to an input terminal of the differential amplification stage.
