Abnormal Profiles Detection Based on Time Series and Target Item Analysis for Recommender Systems

Abnormal Profiles Detection Based on Time Series and Target Item Analysis for Recommender Systems

Collaborative filtering (CF) recommenders are vulnerable to shilling attacks designed to affect predictions because of financial reasons. Previous work related to robustness of recommender systems has focused on detecting profiles. Most approaches focus on profile classification but ignore the group...
