@kevin1 Thanks for sharing those. And glad you found that article both “well written” and “technical.” That means a lot coming from you! I’ll tell my mom she did a good job teaching me how to write 
@jamieeburgess I hope kevin’s post lends some clarity to the difficulty. We have some great minds in data science and machine learning here. If a training mode was possible to do right now, there would be no reason not to do it. It’s probably the most asked for feature!
