A Bayesian Inference based Hybrid Recommender System

Armielle Noulapeu Ngaffo, Walid El Ayeb, Zied Choukair
2020 IEEE Access  
In this paper, we propose a hybrid model-based recommendation approach, a combination of a user-based approach and an item-based approach.  ...  It performs a Bayesian inference of future end-user interests and shows the advantage of the easy-understandability of memory-based methods and the effectiveness of model-based methods.  ...  To alleviate the item targeting problem, in this paper, we propose a hybrid recommender system that uses Bayesian estimation to predict users' interests.  ...

Learning multiple models for exploiting predictive heterogeneity in recommender systems

Clinton Jones, Joydeep Ghosh, Aayush Sharma
2011 Proceedings of the 2nd International Workshop on Information Heterogeneity and Fusion in Recommender Systems - HetRec '11  
Such predictive heterogeneity is likely to occur in large recommender systems that involve a diverse set of users, and can be mitigated by using multiple localized predictive models rather than a single  ...  The proposed approach can incorporate different types of inputs to predict the preferences of diverse users and items.  ...  The use of user and item vectors whose elements correspond exactly to one another is common in content-based recommendation systems [6] .  ...

Empirical Analysis of Predictive Algorithms for Collaborative Filtering [article]

John S. Breese, David Heckerman, Carl Kadie
2013 arXiv   pre-print
Collaborative filtering or recommender systems use a database about user preferences to predict additional topics or products a new user might like.  ...  This metric uses an estimate of the probability that a user will see a recommendation in an ordered list.  ...  Max Chickering, David Hovel, and Robert Rounthwaite contributed to the programming of the algorithms that were used in this study.  ...

Geoffrey Gitonga, Wilson Cheruiyot, Waweru Mwangi
2015 International Journal of Computer Applications Technology and Research  
Association rule mining method has been widely used in recommender systems in profiling and generating users' preferences.  ...  These vices could be managed using recommender systems methods which are used to deliver users' preference data based on their previous interests and in relation with the community around the user.  ...  Due to internet development and the increase in the number of users, recommender systems for web applications were introduced to anticipate users' preferences in terms of content and information based  ...

You are what you consume

Konstantinos Babas, Georgios Chalkiadakis, Evangelos Tripolitakis
2013 Proceedings of the 7th ACM conference on Recommender systems - RecSys '13  
In our approach, we model both user preferences and items under recommendation as multivariate Gaussian distributions; and make use of Normal-Inverse Wishart priors to model the recommendation agent beliefs  ...  We then interpret these ratings in an innovative way, using them to guide a Bayesian updating process that helps us both capture a user's current mood, and maintain her overall user type.  ...  Research in recommendation systems attempts to understand a user's needs, preferences and mood, and help her make a decision.  ...
