An Effective Threshold-Based Neighbor Selection in Collaborative Filtering
نویسندگان
چکیده
In this paper we present a recommender system using an effective threshold-based neighbor selection in collaborative filtering. The proposed method uses the substitute neighbors of the test customer who may have an unusual preferences or who are the first rater. The experimental results show that the recommender systems using the proposed method find the proper neighbors and give a good prediction quality.

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 کاملA Neighbor Selection Method Based on Priority of the Number of Common Items in Collaborative Filtering
Memory-based collaborative filtering (MBCF) selects the top-k neighbors in order to predict a rating for an item the target user has not yet experienced. We propose a method to minimize the similarity errors with the existing neighbor selection method by considering the number of common items between two objects. To verify the proposed method, we compare experimental results on the existing met...
