Need for algorithms that improve novelty, diversity or longtail

[abdollahpouri]

Hello
I was trying to find some algorithms that are designed to improve novelty, diversity or long-tail of the recommendations but I was not able to find those in Librec. I think all the algorithms implemented in Librec are baselines that are designed to give more accurate recommendations. But since other factors like novelty and diversity are also very important I think it would be useful if you have some of those algorithms too implemented in your library. Please let me know if I am wrong and you already have implemented some of those algorithms.
