On second thought, I would say start with smaller models and work your way up. More complicated models take much longer to train, and keep training them until they plateau. Turn off the overlay and train on fast speed to get there faster. Once you are satisfied with a model, change one thing and see how much of an improvement you get, but it is a time-consuming process. I have not fiddled with any of the "opt." options yet.
