Abstract: The relevance or ranking of various dynamically-determined instances of content can be adjusted or otherwise improved based on aspects such as the freshness or seasonality of the content. In many conventional relevance or ranking algorithms, factors such as popularity, performance, and profit are used to determine which content to present to a user, as well as how to display the selected content. Such algorithms do not necessarily reflect domain-specific knowledge very well, and thus fail to accurately select content that is of differing levels appeal at various ages of the content and/or during various seasons of the year. Freshness and/or seasonality adjustment scores can be used to generate improved relevance, selection, or ranking determinations for various categories of content.

Abstract: A computer-implemented system stores profiles for parties to the negotiation, each profile specifying values for one or more parameters negotiated, the values reflecting a desirable outcome of the negotiation for the associated party. A matching server accesses an offer from a first party containing values for one or more of the parameters negotiated and computes a distance between the offer values and the profile values of a second party. If the distance is acceptably small, the server causes the offer to be accepted by the second party to conclude the negotiation. If the distance is not acceptably small, the server automatically modifies one or more values in the offer such that the distances between the modified offer and the profiles of the first and second parties are acceptably small simultaneously and causes the modified offer to be accepted by the first and second parties to conclude the automatic negotiation.

Abstract: This invention provides a system and method for determining the level of clutter in an image in a manner that is rapid, and that allows a scoring process to quickly determine whether an image is above or below an acceptable level of clutter—for example to determine if the underlying imaged runtime object surface is defective without need to perform a more in-depth analysis of the features of the image. The system and method employs clutter test points that are associated with regions on the image that should contain a low gradient magnitude, indicative of emptiness. This enables the runtime image to be analyzed quickly by mapping trained clutter test points at locations in the coordinate space in which lack of emptiness indicates clutter, and if detected, can rapidly indicate differences and/or defects that allow for the subject of the image to be accepted or rejected without further image analysis.

Abstract: The current document is directed to digital-image-normalization methods and systems that generate accurate intensity mappings between the intensities in two digital images. The intensity mapping generated from two digital images is used to normalize or adjust the intensities in one image in order to produce a pair of normalized digital images to which various types of change-detection methodologies can be applied in order to extract differential data. In one approach, a mapping model is selected to provide a basis for statistically meaningful intensity normalization. In this implementation, a genetic optimization approach is used to determine and refine model parameters. The implementation produces a hybrid intensity mapping that includes both intensity mappings calculated by application of the mapping model and intensity mappings obtained directly from comparison of the images.
