A scalable privacy-preserving recommendation scheme via bisecting k-means clustering

作者:

Highlights:

• A novel bisecting k-means clustering-based privacy-preserving CF scheme is proposed.

• A two-level preprocessing scheme is suggested to enhance scalability and accuracy.

• Effects of scalability and sparseness challenges are alleviated considerably.

• Accuracy of the solution is significantly better than knn-based CF and PPCF methods.
