  • Patent number: 10242381
    Abstract: Technologies for optimized selection of content for delivery to a user that both optimizes the expected return from the delivery of the content to the user and that enables exploration of delivery of new content to users are disclosed. Content is selected for delivery to a user based on an exploitation score that defines an estimate of the feedback expected from the delivery of the content to the user and an exploration score that varies inversely with the number of times that the content has been transmitted to all users. The use of the exploration score enables the exploration of delivery of new content to users. The content might be delivered via e-mail messages, a web site, or using another mechanism.

  • Patent number: 10162868
    Abstract: Data mining systems and methods are disclosed for evaluating pairwise substitutability relationships among items. For example, a pairwise similarity measure may correspond to a value quantifying the extent to which an item A is favored over an item B by a population of users. Given a base item selected by a user, the system may select a candidate item from a set of potential substitute items for the base item based on current estimates of corresponding pairwise similarities. The system may then present the candidate item to the user in a context of comparison against the base item and obtain an indication of user preference between the two. The system may then update corresponding pairwise similarities based on the indication of preference.

  • Patent number: 10049375
    Abstract: A system is disclosed that identifies early adopter users by creating a directed graph of item access information for an item category and performing a page rank type process on the item access information. This directed graph may be created in a reverse temporal order. The early adopter users can be identified as the users with nodes in the directed graph that have a threshold number or rate of incoming links directly or indirectly pointing towards the nodes. Using the early adopter users as a sample, systems herein can determine whether to recommend an item based on the popularity of the item with respect to the early adopter users. Further, systems herein can determine an inventory level to maintain for an item based on the popularity of the item with respect to the early adopter users.
