  • Publication number: 20240169411
    Abstract: A computerized system and method for dynamically generating modified user interface is disclosed. The method comprises receiving a search request, providing a list of at least one product in response to the search request, receiving a selection of a first product from the user device, providing the first product to the user device for display on the user interface, determining signals of the first product and their weights, calculating a score for each of the second products based on signals of the first product, ranking the second products by the score, and in response to receiving a request to redisplay the list of product, providing, to the user device for display together with the list of product, at least one second product based on the ranking.

  • Patent number: 11354721
    Abstract: Systems and methods are provided for providing product recommendations, comprising receiving, from a user device, a search query, defining, using a query handler cluster, context associated with the search query, identifying, using a search cluster, one or more products associated with the defined context, filtering, using the search cluster, the one or more products associated with the defined context based on features associated with the one or more products stored in a database, ranking, using the search cluster, the one or more products associated with the defined context based on a score generated for each product, and displaying, on the user device, product recommendations, wherein the product recommendations comprise a number of the one or more ranked products.

  • Publication number: 20200338609
    Abstract: The present invention discloses a method for channel decoupling of a whole-roller flatness meter for a cold-rolled strip. The method includes the following steps: 1, setting a channel number and a channel breadth of the flatness meter; 2, obtaining an influence matrix under the condition of coupled channels; 3, calculating an inverse matrix of the influence matrix; 4, decoupling the channel by the inverse matrix of the influence matrix; and 5, obtaining flatness distribution after channel decoupling. The present invention decouples the channel of the whole-roller flatness meter by inverting the influence matrix and multiplying with the detection force vector. The present invention reproduces the true force vector and flatness distribution, and provides a new method for improving the flatness detection accuracy.
