I've seen the classifications of other algorithms and they fall prey to the distortions of makeup. For example an average looking woman with makeup accentuating features, particularly dark eyebrows and eyelashes, will score higher than a beautiful woman without. The fact that the score can be affected by image quality suggests it's using the same sort of NN features. Better features for beauty are symmetry, facial width to height ratio, unblemished skin, bone structure, etc. ANNs tend not to understand morphology without deliberate preprocessing (e.g. by someone deciding it's a network feature worth calculation), so many of these things can be missed.

You want to make something out of (name any substance)? There are only a few special cases where any government approval is required, and patents are NEVER required.

If you want any capital to operate with, you need security in the profitability of producing it. Patents are this security, and so are always necessary unless you want to throw money away. So no, you don't want to leave out steps that will quickly leave your company bankrupt. And all business sectors have codes, standards, and regulations by which you need to abide.

There are a hundred steps in between the lab and the open market. You need a lot of funding, development and approval of patents, the approval from applicable government agencies, prototyping, mass production, marketing, and then if all that is successful, market penetration. This doesn't happen in a year. Hopefully it's highly profitable too, or its time on the market will be short-lived.

Galaxy hopping is not as improbable as you would think. It's a matter of developing better propulsion systems, something I'm sure we'll do. You might have heard it said that at 1g constant acceleration, you could reach Andromeda in under 40 years, ship-time. Man would need to master antimatter and suspended animation, but even today that doesn't seem like magic.

What the world *really* needs is a good Automatic Bicycle Sharpener.
