You can render it from lots of different angles, | lighting conditions, backgrounds, stretched out, curled up, | etc. You know the ground truth classification on all | renderings is that the picture contains a lion, but being | able to generate images of lions is a very different task | from recognizing lions in images. | ausbah wrote: | at least in the case of reinforcement learning, no. just | because you can simulate the problem doesn't mean you know how | to optimally solve it - ex driving a car | btdmaster wrote: | Not necessarily: | https://en.wikipedia.org/wiki/Data_augmentation | SomewhatLikely wrote: | Pretty clickbaity. Lots of "some argue", "some say", "has | estimated", and "striving to", but not much substance about | actual successes. I believe both Tesla and Cruise are working in | this direction but there are serious issues to be worked out. I | also vaguely remember some work on pose estimation being helped | by generating renderings. Going over real successes would make | for a more convincing article. | sockpuppet69 wrote: ___________________________________________________________________ (page generated 2022-02-18 23:00 UTC)
