## OPT2019

We welcome you to participate in the 11th OPT Workshop on Optimization for Machine Learning. This year's OPT workshop will be run as an independent event, co-located with NeurIPS in Vancouver. It will happen on December 14th, overlapping with the NeurIPS workshops, to facilitate easy switching between the two venues for attendees.

We are looking forward to an exciting OPT 2019!

**Location: Exchange Hotel Vancouver**

### Location

**Exchange Hotel Vancouver (5th floor, Townley Studio)** (a short 5 minutes walk from the conference center)
