Abstract: Similarity sensitive diversity is utilized to measure variation in a distribution of item listings along one or more categories. A similarity between category vectors of each category pair in a set of categories is determined and utilized to generate a pairwise similarity matrix. The pairwise similarity matrix may be pruned to remove category pairs below a threshold. Utilizing the pairwise similarity matrix, similarity sensitive diversity between one or more items of a plurality of items may be determined. In various aspects, the similarity sensitive diversity may be utilized to: generate a list of relevant items in an appropriate distribution, suggest refinements of a search query; generate navigation modules; categorize or recategorize the plurality of items; or generate autosuggestions.

Abstract: The invention provides 3D-knitted spacer fabrics of high breathability and moisture management and methods of making the 3D-knitted spacer fabrics. The middle layer of the fabric is made of hydrophilic material, comprising two yarns, a blended thermo-fuse wicking yarn comprising hydrophilic fiber and thermo-fuse fiber, and a non-supportive hydrophilic functional wicking yarn. The top layer of the fabric comprises a hydrophilic yarn, and the third layer of the fabric comprises a hydrophobic yarn. The 3D-knitted spacer fabrics are useful in clothing and equipment for wear in high temperature environments.

Abstract: A computing system generates recommendations for users within the context of a network service. To account for objectives of various users associated with the network service, some of which may not reach optimality at the same time, the computing system generates values associated with each of the objectives separately. For example, for each objective, the system may train a computer model to produce a representative value. To generate a recommendation of an entity for a user, the system uses the generated objective values as inputs to an optimization algorithm. The optimization step may use linear programming or quadratic programming to generate a recommendation score, for example. This two-step process allows the system to account for multiple objectives and makes the system easily adaptable to change when the set of objectives is updated.
