Abstract: An electronic device is provided. The electronic device includes: a memory storing a neural network model; and a processor configured to: obtain a plurality of individual graphs based on an access history for a plurality of contents over a plurality of sessions; generate an integrated graph, in which the plurality of individual graphs are integrated, based on a connection relationship between nodes included in the plurality of individual graphs and a number of times each connection between the nodes is repeated; obtain a plurality of augmented graphs by augmenting each of the plurality of individual graphs based on the integrated graph; and train the neural network model to provide recommended content based on the plurality of augmented graphs.

Abstract: An electronic apparatus is provided. The electronic apparatus includes a memory configured to store at least one command and a processor connected to the memory and configured to control the electronic apparatus. The processor is configured to, by executing the at least one command, obtain graph information for a plurality of users in which viewing content is arranged in a time sequence based on content viewing history information for a plurality of users, obtain attribute information for each content by inputting the graph information for the plurality of users to a Graph Neural Network (GNN) model, group the plurality of users into a plurality of viewing groups based on the graph information for the plurality of users and the attribute information for each content, and provide a recommended content based on content information corresponding to the plurality of viewing groups.

Abstract: An operation method for reducing energy consumption and an electronic apparatus thereof are provided. The operation method includes obtaining, by the electronic apparatus, weather forecast information, inputting, by the electronic apparatus, the weather forecast information to an artificial intelligence model for predicting an amount of power to be consumed by a first air conditioner, and displaying, by the electronic apparatus, the predicted power consumption amount of the first air conditioner output from the artificial intelligence model, wherein the artificial intelligence model is trained to obtain correlation information between a weather condition and a power consumption amount of an air conditioner, based on a weather history and operations of a plurality of air conditioners related to the weather history, and predict the amount of power to be consumed by the first air conditioner based on the correlation information and the weather forecast information.
