This year, the third instance of the MLUI workshop will kick off the IEEE VIS conference on Sunday morning from 8:00-11:30 MDT. Attendance to the workshop is open to everyone and free with the accompanying registration for IEEE VIS (http://ieeevis.org). This year, we have two excellent keynote speakers to begin each session. In the first session, Michael Sedlmair will present "Machine Learning meets Visualization," discussing how the two fields can work together for mutual benefit. In the second session, Alvitta Ottley will present "Using Models and Predictions to Help Humans and Computers Click," discussing the current state and future of research in user modeling for data visualization. Each session will also contain shorter research talks, as well as some dedicated time for discussion. More information about the workshop and the talks can be found on the workshop website: learningfromusersworkshop.github.io. We would be pleased to have you join us!
