Social-aware recommendation approaches have been recognized as an effective way to solve the data sparsity issue of traditional recommender systems. The assumption behind is that the knowledge in social user-user connections can be shared and transferred to the domain of user-item interactions, whereby to help learn user preferences. However, most existing approaches merely adopt the first-order connections among users during transfer learning, ignoring those connections in higher orders. We…

A Neural Influence Diffusion Model for Social Recommendation
TLDR
A deep influence propagation model is proposed to stimulate how users are influenced by the recursive social diffusion process for social recommendation, with more than 13% performance improvements over the best baselines for top-10 recommendation on the two datasets.
An Efficient Adaptive Transfer Neural Network for Social-aware Recommendation
TLDR
An Efficient Adaptive Transfer Neural Network (EATNN) is proposed that consistently outperforms the state-of-the-art methods on Top-K recommendation task, especially for cold-start users who have few item interactions and shows significant advantages in training efficiency.
Social Attentional Memory Network: Modeling Aspect- and Friend-Level Differences in Recommendation
TLDR
An attention-based memory module is designed to learn user-friend relation vectors, which can capture the varying aspect attentions that a user share with his different friends, and a friend-level attention component is built to adaptively select informative friends for user modeling.
Leveraging Social Connections to Improve Personalized Ranking for Collaborative Filtering
TLDR
A model, SBPR (Social Bayesian Personalized Ranking), is developed based on the simple observation that users tend to assign higher ranks to items that their friends prefer, and it is shown that SBPR outperforms alternatives in ranking prediction both in warm- and cold-start settings.
Semantic Path based Personalized Recommendation on Weighted Heterogeneous Information Networks
TLDR
This paper is the first to propose the weighted HIN and weighted meta path concepts to subtly depict the path semantics through distinguishing different link attribute values, and proposes a semantic path based personalized recommendation method SemRec to predict the rating scores of users on items.
DeepInf: Social Influence Prediction with Deep Learning
TLDR
Inspired by the recent success of deep neural networks in a wide range of computing applications, an end-to-end framework to learn users' latent feature representation for predicting social influence is designed, suggesting the effectiveness of representation learning for social applications.
Factorization meets the neighborhood: a multifaceted collaborative filtering model
TLDR
The factor and neighborhood models can now be smoothly merged, thereby building a more accurate combined model and a new evaluation metric is suggested, which highlights the differences among methods, based on their performance at a top-K recommendation task.
Selective Transfer Learning for Cross Domain Recommendation
TLDR
This paper proposes a novel criterion based on empirical prediction error and its variance to better capture the consistency across domains in CF settings and embeds this criterion into a boosting framework to perform selective knowledge transfer.
TrustSVD: Collaborative Filtering with Both the Explicit and Implicit Influence of User Trust and of Item Ratings
TLDR
This work proposes TrustSVD, a trust-based matrix factorization technique that is the first to extend SVD++ with social trust information and achieves better accuracy than other ten counterparts, and can better handle the concerned issues.
Collaborative Filtering for Implicit Feedback Datasets
TLDR
This work identifies unique properties of implicit feedback datasets and proposes treating the data as indication of positive and negative preference associated with vastly varying confidence levels, which leads to a factor model which is especially tailored for implicit feedback recommenders.
