  • Publication number: 20190221973
    Abstract: An electrical connector for high speed signals. The connector has multiple conductive elements that may serve as signal or ground conductors. A member formed with lossy material and conductive compliant members may be inserted in the connector. The conductive compliant members may be aligned with conductive elements of the connector configured as ground conductors. For a connector configured to carry differential signals, the ground conductors may separate pairs of signal conductors. The member may further include a conductive web, embedded within the lossy material, that interconnects the conductive compliant members. For a receptacle connector, the conductive elements may have mating contact portions aligned along opposing surfaces of a cavity. The conductive elements may have contact tails for attachment to a printed circuit board and intermediate portions connecting the mating contact portions and the contact tails. The conductive compliant members may press against the intermediate portions.

  • Publication number: 20190080246
    Abstract: Systems, methods, and computer-readable storage media that may be used to generate a category Bayesian hierarchical model. One method includes receiving a brand data set for each of a plurality of brands within a category, each brand data set comprising content input for a particular brand of the plurality of brands for a plurality of media channels at a plurality of times and a response for the particular brand of the plurality of brands at the plurality of times. The method includes determining a plurality of informative priors by generating a category Bayesian hierarchical model based on the plurality of brand data sets and a plurality of weak priors. The method further includes generating a brand Bayesian hierarchical model that models response for the particular brand for each of the plurality of media channels based on the brand data set for the particular brand and the plurality of informative priors.

  • Publication number: 20190065638
    Abstract: Systems, methods, and computer-readable storage media that may be used to generate a Bayesian hierarchical model. One method includes generating a plurality of geographic regions by grouping one or more geographic sub-regions into each of the plurality of geographic regions. The method further includes receiving data for the geographic sub-regions, the data including responses, content inputs, content types, and location identifiers. The method further includes generating geo-level data from the received data by grouping the responses and content inputs of the received data based on a correlation of the location identifiers of the received data to the plurality of geographic regions. The method includes fitting a Bayesian hierarchical model based on at least the geo-level data, the content types, and the geographic regions and determining a content input mix for the content types for each geographic region based on the Bayesian hierarchical model and a content input constraint.
