The purpose of recommendation systems is to help users find effective information quickly and conveniently and also to present the items that users are interested in. While the literature of recommendation algorithms is vast, most collaborative filtering recommendation approaches attain low recommendation accuracies and are also unable to track temporal changes of preferences. Additionally, previous differential clustering evolution processes relied on a single-layer network and used a single scalar quantity to characterise the status values of users and items. To address these limitations, this paper proposes an effective collaborative filtering recommendation algorithm based on a double-layer network. This algorithm is capable of fully exploring dynamical changes of user preference over time and integrates the user and item layers via an attention mechanism to build a double-layer network model. Experiments on Movielens, CiaoDVD, and Filmtrust datasets verify the effectiveness of our proposed algorithm. Experimental results show that our proposed algorithm can attain a better performance than other state-of-the-art algorithms.

Abstract Based on self-attention and outer product-based neural collaborative filtering,this paper proposed a SLAR model.The model uses the recent interaction information of each user in the group and self-attention mechanism to obtain the short-term interest vector of the group.The attention mechanism and self-attention mechanism are used to calculate the influence of each user and the influence between members during the interaction between the target group and item, so as to aggregate them into the long-term preference vector of the group, and then the sum of short-term interest and long-term preference is input into ONCF model as the embedding vector of the group to mine the interaction between the group and the project from the data, and finally complete the group recommendation. Compared with the traditional group fusion strategy on CAMR2011 data set, the experimental results show that SLGR model achieves better results.

Aerobics is full of charm, and music plays an inestimable role in it. With the penetration of music in aerobics, the “sound” of music art is introduced into the “shape” of aerobics movements, and the visual art and visual experience are perfectly combined, which greatly expands the extension and extension of aerobics. This paper proposes an aerobics music adaptation recommendation algorithm that combines classification and collaborative filtering. First, by calculating the similarity of the user context information, the collaborative filtering algorithm obtains the initial annihilation grass music recommendation list; then the classification model is trained by the machine learning algorithm to obtain the user’s aerobics music type preference in a specific context; finally, collaborative filtering The obtained recommendation list is integrated with the aerobics music preference obtained by the classification model to provide personalized aerobics music adaptation recommendations for users in specific situations. In the specific aerobics music adaptation recommendation, the algorithm is implemented by a deep neural network composed of an independent cyclic neural network algorithm and an attention mechanism. In the data preprocessing stage, the audio of the user’s listening history is preprocessed by scattering transformation. The audio features of the user’s listening history are extracted by scattering transformation, and then this feature is combined with the user’s portrait to obtain a recommendation list through an independent recurrent neural network with a hybrid attention mechanism. The experimental results show that this method can effectively improve the performance of the personalized music recommendation system. Compared with the traditional single algorithm IndRNN and LSTM, the recommendation accuracy is improved by 7.8% and 20.9%, respectively.
