SVD-based Privacy Preserving Data Updating in Collaborative Filtering
Collaborative Filtering technique is widely adopted by online service providers in their recommender systems. This technique provides recommendations based on users’ transaction history. To provide decent recommendations, many online merchants (data owner) ask a third party to help develop and maintain recommender systems instead of doing that themselves. Therefore, they need to share their dat...
متن کاملA New Similarity Measure Based on Item Proximity and Closeness for Collaborative Filtering Recommendation
Recommender systems utilize information retrieval and machine learning techniques for filtering information and can predict whether a user would like an unseen item. User similarity measurement plays an important role in collaborative filtering based recommender systems. In order to improve accuracy of traditional user based collaborative filtering techniques under new user cold-start problem a...
متن کاملCollaborative Filtering through SVD-Based and Hierarchical Nonlinear PCA
In this paper, we describe and compare two distinct algorithms aiming at the low-rank approximation of a user-item ratings matrix in the context of Collaborative Filtering (CF). The first one implements standard Principal Component Analysis (PCA) of an association matrix formed from the original data. The second algorithm is based on h-NLPCA, a nonlinear generalization of standard PCA, which ut...
متن کاملPrivacy Protection in Memory-Based Collaborative Filtering
We discuss the issue of privacy protection in collaborative filtering, focusing on the commonly-used memory-based approach. We show that the two main steps in collaborative filtering, being the determination of similarities and the prediction of ratings, can be performed on encrypted profiles, thereby securing the users’ private data. We list a number of variants of the similarity measures and ...
متن کاملPrivacy-Enhanced Collaborative Filtering
Current implementations of the Collaborative Filtering (CF) algorithm are mostly centralized and the information about users (their profiles) is stored in a single server. Centralized storage poses a severe privacy hazard, since user profiles are fully under the control of the recommendation service providers. These profiles are available to other users upon request and are transferred over the...
