Hi, I'm not part of the dev team but as my question relates directly to mahout (taste) code I'm sending that email to the dev team.
When using a cachingRecommender, if recommendations are requested for an anonymous user (using a plusAnonymousDataModel) I wondered if caching those recommendations was not a waste of a cache entry (as the user is temporary). So, does it makes sense to add in the *recommend* method of the CachingRecommender class a filter that will not cache the recommendation of a user having the id Long.MIN_VALUE (which is the user id of a temporary user as I saw in the PlusAnonymousUserDataModel class)? Thanks, Philippe Adjiman.
