  • Patent number: 11849188
    Abstract: In some embodiments, a method receives information for a delivery of instances of supplemental content for a plurality of line items. A line item is associated with an instance of supplemental content that can be delivered and a pacing curve that describes a pace of delivery over time. The method updates a parameter for the line item to generate an updated parameter based on the delivery of the instances of supplemental content and a desired pacing behavior. The updated parameter is provided to a selection system that uses the updated parameter to select an instance for delivery. The delivery of instances of supplemental content for the line item is adjusted to meet the pacing curve based on a characteristic of the pacing behavior.

  • Patent number: 11671668
    Abstract: In some embodiments, a method receives a first set of probabilities mapping a behavior to a user for a set of behaviors in a video delivery system. A first part of a model is used to predict the first set of probabilities. The method receives a second set of probabilities mapping a user to a behavior for a set of users that are using an account on the video delivery system. A second part of the model is used to predict the second set of probabilities. A combined probability is calculated for the set of behaviors and the set of users based on the first set of probabilities and the second set of probabilities. The method updates a second parameter of the second part of the model while keeping a first parameter of the first part of the model fixed and outputs the second parameter of the second part of the model upon determining the training of the model is finished.

  • Patent number: 11553220
    Abstract: In some embodiments, a method receives an supplemental content placement and a context associated with a request for supplemental content to be displayed for the supplemental content placement. A first value is generated based on the context using a prediction network for a platform. The method determines probabilities for a plurality of types of request actions based on the context. Then, a threshold for the supplemental content placement is calculated based on the first value and the probabilities for the plurality of types of request actions. The method submits the threshold to a platform in a request for the platform to submit a second value for the supplemental content placement.

  • Publication number: 20160237237
    Abstract: In some embodiments, the present disclosure pertains to gas barrier composites that include a polymer matrix and graphene nanoribbons dispersed in the polymer matrix. The polymer matrix can include a phase-separated block copolymer with a hard phase domain and a soft phase domain. Like-wise, the functionalized graphene nanoribbons can include edge-functionalized graphene nanoribbons with concentrations that range from about 0.1% by weight to about 5% by weight of the gas barrier composites. In some embodiments, the present disclosure pertains to methods of making gas barrier composites by dispersing graphene nanoribbons in a polymer matrix. In some embodiments, the dispersing lowers the permeability of a gas through the gas barrier composite and causes phase separation of block copolymers in the polymer matrix. In some embodiments, the dispersion of graphene nanoribbons in the polymer matrix lowers the gas effective diffusivity of the gas barrier composite by three orders of magnitude.
