  • Group item recommendations for ephemeral groups based on mutual information maximization
    Patent number: 11443346
    Abstract: A computer-implemented method is disclosed for training neural networks of a group recommender to provide item recommendations for ephemeral groups having group interaction sparsity. A preference encoder and aggregator generate user and group preference embeddings from user-item interactions, wherein the preference embeddings form a latent user-group latent embedding space.

  • DYNAMIC GRAPH REPRESENTATION LEARNING VIA ATTENTION NETWORKS
    Publication number: 20210326389
    Abstract: A method includes extracting, by an analysis computer, a plurality of first datasets from a plurality of graph snapshots using a structural self-attention module. The analysis computer can then extract at least a second dataset from the plurality of first datasets using a temporal self-attention module across the plurality of graph snapshots. The analysis computer can then perform graph context prediction with at least the second dataset.
