Rails 中的协同过滤
我正在寻找一种在 Rails 中进行协作过滤的解决方案，甚至是可能的示例。到目前为止，我只找到了acts_as_recommendable，它看起来很有用，但我注意到它在过去两年里没有任何更新。
有谁知道任何其他解决方案和/或示例？
I'm looking for a solution for collaborative filtering in rails or even possible examples. So far I have only found acts_as_recommendable which looks useful but I noticed it hasn't had any updates in the last 2 years.
Does anyone know of any other solutions and/or examples?

这是 Ruby 中的 50 行推荐系统： http: //www.igvita.com/2007/01/15/svd-recommendation-system-in-ruby/
那里有一个链接不起作用（当他说“mathies click here”时，它指向Berry 等人使用线性代数进行智能信息检索：http://www2.denizyuret。 com/ref/berry/berry95using.pdf）
here is a 50 line recommendation system in Ruby: http://www.igvita.com/2007/01/15/svd-recommendation-system-in-ruby/
