Abstract: In an aspect, a request to display information on a client device of a user can be received. A plurality of features associated with the request can be extracted. The plurality of features can include at least one feature characterizing the user and at least an additional feature characterizing the client device. A feature vector based on the features associated with the request can be generated. A predicted response value of the user to a content presentation can be generated using a predictive model and the feature vector. The predicted response value can characterize a likelihood of the user interacting with the content presentation. A request response value can be determined based on a content presentation impression value and the feature vector. The request response value and the content presentation can be transmitted for display on the client device of the user.

Abstract: A method to optimize recategorization of financial transactions using collaborative filtering involves obtaining a set of financial transactions of a set of users with a merchant. The method also involves determining, using a processor, a first portion of the set of financial transactions assigned to each recategorization value of a set of recategorization values; determining, using the processor, a second portion of the set of financial transactions where the each recategorization value is different from an initial category; generating, using the processor, a recategorization index for each recategorization value using the first portion of each recategorization value and the second portion; and determining, using the processor, an alternative categorization candidate based on the recategorization index of the each recategorization value.

Abstract: A structured document file which includes graphical and non graphical information. The graphical information includes the vector and coordinate description of a representation of at least one three dimensional object and at least one of the following group of view attributes or features: rotation, translation, view angle, lighting, colors, specific graphical representations, labels and parameters. The vector and coordinate description are stored with or independently from the one or more view attributes or features and the vector and coordinate description and the one or more view attributes are stored in a single file which can be accessed and viewed by a structured document viewer. Related authoring tools and viewers are also disclosed.
