A Neural Matrix Decomposition Recommender System Model based on the Multimodal Large Language Model

The challenge of finding content that aligns with users' interests within this abundance has become increasingly important. Recommender systems play a crucial role in addressing this issue, as they have the potential to provide precise recommendations that enhance user experience and save time in commercial applications [1]. These systems predict user ratings for specific items by employing data mining techniques and related predictive algorithms to make highly relevant predictions. By analyzing user historical behavior, preferences, and item characteristics, recommender systems effectively solve the information filtering problem by automatically matching items that may be of interest to users. Traditional recommender systems primarily consist of collaborative filtering [2], content-based recommendations [3], and hybrid recommendation methods, among which collaborative filtering is one of the earliest and most widely used techniques for recommending products or items based on past purchasing history.
