------------------------------------
Hi,Sebastian,
We have think about that ,but for commerce system ,the invalid data is very
much and some has very high score and very popular.
even we compute 10 times as much recommended items as we need,it maybe all of
them are invalid.
> Can add one parameter --itemsFile for
> org.apache.mahout.cf.taste.hadoop.item.RecommenderJob

> Can add one parameter --itemsFile for
> org.apache.mahout.cf.taste.hadoop.item.RecommenderJob ?
> --itemsFile some likes the the --usersFile.
> in some case, we want to calculate similarity using all preferences data ,
> but some item in preferences are old ,not available,behind the times or
> retired ,
> we want that those data can not recommend to users, can only recommend user
> with new or valid items.
> so we can add on paramete --itemsFile for RecommenderJob, itemsFile includes
> all the new valid items.
