The IEEE VIS workshop EVIVA-ML on evaluation of Interactive Visual Machine Learning (IVML*) systems will feature an exciting panel to discuss key challenges and future directions for IVML evaluation. The panel includes leading researchers in visualization and interactive machine learning: Enrico Bertini, Remco Chang, Christopher Collins, Steven Drucker, Alex Endert, Jessica Hullman, Chris North, Michael Sedlmair. If you would like to share your views and comments on the evaluation of IVML systems with the visualisation community, please fill in this short survey (5-10 minutes): https://drive.google.com/open?id=1RpLIfXZ6qMfL0VTYX9EG6-bzClyF6NLPjFODpZERih... This survey will help extract general topics to discuss during the workshop panel. Thanks in advance for your help!
