  • Publication number: 20230385607
    Abstract: An electronic device and a method for implementation of hypergraph-based collaborative filtering recommendations. The electronic device receives a collaborative filtering graph corresponding to a set of users and a set of items. The electronic device determines a first set of user embeddings and a first set of item embeddings. The electronic device applies a semantic clustering model to determine a second set of user embeddings and a second set of item embeddings. The electronic device constructs a hypergraph to determine a third set of user embeddings and a third set of item embeddings. The electronic device determines a first contrastive loss and a second contrastive loss to determine a collaborative filtering score. The electronic device determines a recommendation of an item for a user based on the determined collaborative filtering score. The electronic device renders the determined recommended item on a display device.

  • Publication number: 20230319358
    Abstract: An electronic device for generation of recommendations using trust-based embeddings is provided. The electronic device determines first correlation information of a first set of users associated with a first domain. The electronic device generates, based on the first correlation information, a first vector indicating a trust embedding of a first user with respect to the first set of users, in the first domain. The electronic device receives second correlation information associated with a second set of users associated with a second domain. The electronic device utilizes a Graph Attention Network model for the second correlation information to generate a second vector indicative of a trust embedding of the first user, with respect to the second set of users, in the second domain. The electronic device applies a recommendation model on the first vector and the second vector to recommend one or more items to the first user.

  • Publication number: 20230316086
    Abstract: An electronic device and a method for implementation for machine learning model update based on dataset or feature unlearning are disclosed. The electronic device receives a data subset of a first dataset associated with a user. A first machine learning model is trained based on the first dataset. The electronic device trains a second machine learning model based on the received data subset. The electronic device applies a transformation function on the trained first machine learning model based on the trained second machine learning model. The electronic device updates the trained first machine learning model, based on the application of the transformation function. The update of the trained first machine learning model corresponds to an unlearning of at least one of the received data subset or a set of features associated with the second machine learning model.
