Beginner Questions #226

Closed ran88dom99 closed 6 years ago

ran88dom99 commented 6 years ago

Why not convert rankings to ratings with monotonic regression or Platt calibration?

What are rMAE, rRMSE?

Does an R interface package for librec exist?

Does a compiled end user friendly download exist and if not why not?

Hi, @ran88dom99

  1. Rating prediction and item ranking are two different tasks for recommender systems.

  2. They are used to measure the accuracy of predicted ratings.

  3. No R interface so far.

  4. We have upload the core package on Maven.
