The method further can include determining, at least in part by a machine learning model, a respective engagement score for each of the recently viewed items based on one or more first features of the one or more features. The one or more first features can be determined by a correlation analysis of the one or more features in a training process of the machine learning model. The method additionally can include ranking the recently viewed items based on the respective engagement score for each of the recently viewed items. The method also can include transmitting, via a computer network to a user device of the user, the recently viewed items, as ranked, for display on the user device. Other embodiments are disclosed.

Abstract: Photonic units for vector-vector multiplication, matrix-vector multiplication, matrix-matrix multiplication, batch matrix-matrix multiplication, and tensor-tensor multiplication are described. Multiplications are through coherent mixing and square-law detection. There are many dimensions—wavelength, vector mode, quadrature, and three dimensions of space—that can be used to construct photonic accelerators. The encoded input vector or input matrix is fanned out into a desired number of copies and mixed with the corresponding encoded local oscillators containing the weight vectors comprising the weight matrix. Any subset of two (three) dimensions can be used to construct photonic accelerators for matrix-vector (matrix-matrix) multiplications. Multiple dimensions can be combined into a hyperdimension to increase the scalability.

Abstract: Examples provide a system and method for recommending complementary apparel items based on an image of a model wearing an anchor item of apparel. A recommendation manager identifies the category of the complementary item. A per-category similarity definition is used to identify category-specific features used to determine whether a candidate item in the same category as the complementary item is the same or similar to the complementary item. A pre-trained machine learning model is used to calculate feature vectors representing the complementary item and each candidate item. The feature vectors are generated by concatenating feature vector values representing each feature in the plurality of category-specific features for the identified category. The candidates are ranked based on the feature vector values. The highest-ranking candidate items having the greatest degree of similarity to the complementary item are added to a list of recommended items presented to the user.
