I just attended the 2019 Toronto Machine Learning Summit (TMLS) last week - it was a great experience.The community was welcoming,the content was relevant, and it was well organized.
One thing that I appreciated about the event is how down-to-earth it felt. Many conversations started with the person that I sat beside during a session, which doesn't happen often at conferences. People had a range of experience with Machine Learning, but everyone came from a genuine place to learn more about the topic. It's quite different from other conferences that I've attended where the marketing glamour is cranked up - leading to a mass-produced approach, hit-or-miss content, and participants feeling more distant.
