As a figure skater and AI engineer, that venn diagram of my life doesn't often overlap.
That was an interesting paper but I'm confused as to what they actually tried to achieve. I'm also confused how they achieve any turning in a model that has infinite friction on one side and zero friction on the other. My brain is having trouble understanding how such a model could ever achieve anything other than a straight line.
