TL;DR
A novel BADLGRS model is evaluated across four datasets and demonstrates superior performance when compared to existing methods, and consistently outperform existing models in group recommendation tasks.
Abstract
Recommender systems (RS) are commonly used in areas such as online orders, travel, and music to suggest items that match user interests. With the rapid growth of social interactions and online activity, their use has naturally extended to both personal and Group Recommendation Systems. A group recommender system focuses on providing recommendations based on a group's shared preferences, rather than relying on a single individual’s choices. To overcome these challenges, we propose a novel BADLGRS developed. The GRL model was used to construct a tripartite graph representing interactions between the number of items, users, and group interactions. To effectively capture semantic group features, this phase introduces a novel model, GRUANN. The GCN model with two layers was used to learn user preferences under the GPL. A novel BADLGRS model is evaluated across four datasets and demonstrates superior performance when compared to existing methods. Specifically, it achieves accuracies of 0.893, 0.567, and 0.095, and a MAP of 0.095. Finally, the results of the BADLGRS model consistently outperform existing models in group recommendation tasks.
A novel neural network called the Co-occurrence Graph Neural Network (CoGNN), which utilizes two co-occurrence graphs to establish user and item relationships and outperforms various baseline models in terms of recommendation accuracy and algorithm convergence.

This study presents an exploratory LLM-agent-based hybrid recommender system framework, building upon a multi-armed bandit approach, which enables semantic understanding of item content and integrates both short-term and long-term user interaction behaviors for recommendation.

Group recommender systems typically rely on either aggregating individual preferences or treating groups as distinct meta-users. However, these methods often suffer from static aggregation strategies or data sparsity issues within group histories. This paper introduces a novel approach, that relies on a GNN-based archi...

This manuscript introduces a novel attention-based recommender system that leverages heterogeneous information networks (HINs) to extract user and item representations and utilizes a matrix factorization framework to model interactions between users and items with the aim of predicting the ratings of users on items.
The graph convolutional recurrent attention recommender (GCRA-Rec) model is proposed, which integrates the collaborative filtering strength of GCNs with sequential learning and introduces a novel sequence encoder that dynamically weights historical interactions according to their relevance to the current recommendation...
