  • Patent number: 11861538
    Abstract: Strategies for an objective associated with an offering set are obtained. A strategy assigns respective selection probabilities of receiving content associated with the offering set to users of a user population. Strategy optimization iterations are performed with respect to a sub-sample of the population and a subset of the strategies. In a given iteration, weights assigned to the strategies are used to determine aggregated selection probabilities for users, content pertaining to the offering set is presented to users selected based on the aggregated probabilities, and the weights are adjusted based on feedback metrics and an exploration-exploitation tradeoff parameter. Based on weights updated in the iterations, content associated with the offering set is presented to users which were not in the sub-sample.

  • Patent number: 11469703
    Abstract: A circuit system and a circuit control method applied to a motor drive are disclosed. The circuit control method includes the steps of providing a phase-locked circuit unit and providing a PWM control unit. The phase-locked circuit unit enables a first carrier signal and a second carrier signal to have identical amplitudes and starting points. The PWM control unit compares the first carrier signal with a reference signal for controlling a switch. When a load current is independently supplied by at least one DC capacitor, a SVPWM control unit controls an inverter unit for the load current to be zero, thereby reducing DC voltage ripple, operation loss and transient voltage surge.

  • Patent number: 11100125
    Abstract: A migration management service can partition a service and migrate resource data without requiring the resource to be taken offline. The migration management service can receive a request to partition a service into multiple partitioned services that are independent of one another. The request can identify one or more resources associated with each partition. For example, a single service receiving data for resources throughout the world can be divided into multiple regional services, where each regional service is independent of the others. The migration management service can track the status of data while migrating. As new messages are received from resources, the migration management service can determine the migration status of the resources. If the data for a resource is not migrated, the original data store can be used. However, if the data is migrated, the message can be forwarded to the appropriate partition for further processing.
