In order for an agent to fully exploit it's environment it first has to explore that environment, and this is where curiosity becomes useful. In fact, last year there was a paper that tried to introduce curiosity to RL-based learning models [1]
I suspect some sort of cross-pollination of these two areas of research would be useful.
