Not sure about conferences in Europe, but NIPS will likely be held in Montréal in December 2018. NIPS is quite focussed on neural networks and tends to get attended by alot of heavy weights in the industry.

ICML and ~ICRL~ ICLR are pretty good too.

ICLR* (IC Learning Representations) but yeah. I had to check whether there was something called "International Conference on Reinforcement Learning".
