Abstract:

  • The existence of popular objects may yield unreasonable recommendation results.
  • We propose a method called PLUS to adjust user similarities using a power function.
  • We show the superior performance of PLUS by large‐scale validation experiments.
  • PLUS achieves a reasonable tradeoff between recommendation accuracy and diversity.
  • PLUS is robust to similarity measures and consistent between different data sets.
