  • Publication number: 20230351225
    Abstract: A method for predicting a next user selection in an electronic user interface includes receiving, from a user, a sequence of selections of documents and generating, for each document in the sequence, a respective attribute vector. The attribute vector includes a numerical attribute vector portion representative of numerical attributes of the document, a category attribute vector portion representative of category information of the document, a text content vector portion representative of text content of the document, and an image content vector portion representative of an image in the document. The method further includes inputting the attribute vectors of the sequence into a machine learning model, and outputting, to the user, in response to the sequence of selections, a predicted next document selection according to an output of the machine learning model.

  • Publication number: 20230244926
    Abstract: A data augmentation framework enhances the prediction accuracy of tensor completion methods. An array having a set of cells associated with a set of entities is received. Influence metrics of cells from the array are determined based on an influence of the cells on minimizing loss while training a machine learning model. An entity-importance metric is generated for each entity of the set of entities based on the influence metrics. A cell from the array for which to augment the array with a predicted value is identified. The cell is identified based on a sampling of the set of entities that is weighted by the entity-importance metric for each entity of the set of entities.

The patterned retarder includes first retarder patterns which convert the light for a left-eye image transmitted by the polarizing substrate into a first polarized light and second retarder patterns which convert the light for a right-eye image transmitted by the polarizing substrate into a second polarized light. The first retarder patterns have a light axis substantially perpendicular to a light axis of the second retarder patterns. The polarizing substrate includes a polarizing plate which transmits the specific linearly-polarized light of the light incident thereto and a glass fiber reinforced plastic substrate which is attached to the polarizing plate.
