Ask HN: How do you network with people working on machine learning/AI?

ML/AI is an exciting field. One half of it is the technical knowledge. The other half is talking to people in the space and understand real-world problems that they're trying to solve. This is to get into real-world problem solving mode rather than just classifying random images because it's fun.

How do you network? What kind of people do you talk to regularly to keep yourself acquainted with the field and the problems that it can solve very well?
