Thanks, I will take a look at the Implicit Feedback literature to see how
it can apply to my situation. Are you aware of any time aware implicit
feedback models?

No. I don't know of any work on that. I am also not

I was wondering if the collaborative filtering library in Mahout has any
algorithms that incorporate concept drift i.e. time dynamics. From my own
research I have come across the BellKor algorithm called TimeSVD++ and
there is a recent paper using hidden markov models with collaborative
No, time is in the data model but nothing uses it that I know of.

Do you know of any other large scale machine learning platforms that do
incorporate it?

Keep in mind that time dynamics generally have benefit for predicting
ratings. The point is that the average rating for a person goes up and
down over time even if their general taste doesn't change. Likewise for an
item.
If you use implicit feedback and recommend based on recent behavior most
