Abstract: A user preference hierarchy is determined from user response to images. Images may be tagged using machine learning models trained to determine values for images. Products are clustered according to product vectors. Images of products within a cluster are clustered according to composition and groups of images are selected from image clusters for soliciting feedback regarding user preference for products of a cluster. Feedback is used to train a user preference model to estimate affinity for a product vector. A user may provide feedback regarding a price point and products are weighted according to a distribution about the price point. The distribution may be asymmetrical according to direction of movement of the price point. Filters may be dynamically defined and presented to a user based on popularity and frequency of occurrence of attribute-value pairs of search results and based on feedback regarding the search results.

Abstract: Images are tagged with values in an image data hierarchy that is most subjective at its top level and least subjective at its bottom level, such as a hierarchy including style, type, and features for clothing. A user preference hierarchy is determined from user response to images that are tagged. Tagged images may be generated by processing them with machine learning models trained to determine values for images. Product records including images and other data are analyzed to generate attribute vectors that are encoded to generate product vectors. Products are clustered according to their product vectors. Images of products within a cluster are clustered according to composition and groups of images are selected from image clusters for soliciting feedback regarding user preference for products of a cluster. Feedback is used to train a user preference model to estimate user affinity for a product having a given product vector.

Abstract: A system allows people to more easily find products matching their skin tone. The system includes a scanning device to scan one or more spots of a person's skin. For example, three different spots can be scanned. The scan determines a skin-tone identifier for the person's skin. With this skin-tone identifier, the customer can view products that match their skin tone.

Feedback is used to train a user preference model to estimate affinity for a product having a given product vector. A user may provide feedback regarding a price point and products are weighted according to a distribution having a highest value at the price point. The distribution may be asymmetrical according to direction of movement of the price point.

Abstract: A system allows people to more easily find products matching their skin tone. A kiosk at a retail store or other location can assist customers in determining what products are right for them and then purchase them from the retailer. The kiosk can include a scanning device is used to scan one or more spots of a person's skin. For example, three different spots can be scanned. The scan determines a skin-tone identifier for the person's skin. This skin-tone identifier is used by a software program (e.g., executing on a tablet computer) to determine and output a listing of products that are appropriate for the person's skin tone.

Abstract: A system allows people to more easily find products matching their skin tone. The system includes a database that categorizes cosmetic products according to a skin tone color set. The system includes a scanning device to scan one or more spots of a person's skin. For example, three different spots can be scanned. The scan determines a skin-tone identifier for the person's skin. With this skin-tone identifier, the customer can view products that match their skin tone.
