  • Patent number: 11048530
    Abstract: A prediction model may be created to predict future actions likely to be performed by users while interacting with electronic content via user devices. The predictions may be used to streamline access to interface controls or other information to enable the users to facilitate or expedite performance of the predicted actions, while reducing computational demands on computing devices that provide the electronic content by, for example, reducing unnecessary intervening computing actions.
    Type: Grant
    Filed: March 23, 2020
    Date of Patent: June 29, 2021
    Assignee: Amazon Technologies, Inc.
    Inventors: Nikolaos Chatzipanagiotis, Pragyana K. Mishra, Roopesh Ranjan
  • Patent number: 10699203
    Abstract: Systems are provided to select targets for communications, designed to cause or provoke the targets to perform a desired action, using bias-corrected models that predict the effect of such communications on the targets. Data regarding previous actions taken by potential targets for communications—also referred to as “candidates”—can be analyzed to determine whether there is a difference in actions taken by candidates who have received prior communications in comparison with candidates who have not received the prior communications. Biases in the selection of candidates to receive the prior communications can be corrected by weighting the data associated with the selected candidates to more closely match the distribution of candidates not selected to receive the prior communications.

  • Patent number: 10692127
    Abstract: Systems and methods are provided for determining or predicting user demographic information using user behaviors through a Bayesian inference. A computing system may determine demographic information (such as age or gender) of a user based on a Bayesian update and a purchase or other user action by the user. In some embodiments, the computing system may determine the household composition of a user account based on multiple purchases by the user account. The computing system may generate recommendations for the user or the user account based on the demographic information of the user or the household composition of the user account.

  • Patent number: 10447647
    Abstract: Systems and methods are described for attributing credit to individual channels for messages delivered via multi-channel communications. A message may be delivered to a recipient via multiple delivery channels, and the recipient may engage in a conversion event or activity associated with receipt of the message. Each delivery of the message may partially contribute to causing the conversion event, and the incremental contribution of each delivery may be determined. A probability of conversion may be determined based on past message deliveries involving the same or similar messages, recipients, and channels. An impressions path may be generated based on the past message deliveries, and subpaths of the impressions path may be used to isolate the contribution of individual message impressions.

  • Patent number: 10375010
    Abstract: Systems and methods are described for selecting recipients, channels, and messages for delivery via multi-channel communications. A message may be delivered to a recipient via multiple delivery channels, and the recipient may engage in a conversion event or activity associated with the message. Each potential delivery of the message may be associated with an incremental probability of causing the conversion event. The incremental probabilities may be used to determine the channel and recipient with the highest incremental probability of causing a conversion event for a given message, the recipient and message having the highest incremental probability of causing a conversion event when delivered via a given channel, and other combinations. Profiles may be used to compare messages, channels, and recipients in order to predict incremental probabilities, and messaging resources may be allocated according to budgets, cost-benefit analyses, or other criteria.

  • Patent number: 8682563
    Abstract: A system for predicting turbine rub includes a monitoring system configured to form operational values for a turbine based on information received from the turbine and a correlation engine configured to form at least one correlated value from the operating values that correlates a first operating value to a second operating value. The system also includes a variable deriver configured to form at least one derived variable from a one of the operating values and a rub predictor that forms a rub prediction based on the at least one correlated value and the at least one derived value.
