Mar 14th, 2017: Deep Learning
Anything you can do they can do better,
They can do anything better than you. Not you, humans. They are computers used to design things, especially 3-D printed things. Quote:

The computer calculates the stresses, knows the material's strength and calculates what is needed. Fine, but what is the calculation using for data? Tables somebody gave it? Are the accurate? If you tell it to design for maximum weight savings you get a design the is just strong enough for the parameters it's given. If you tell it to program for low cost it depends on the data for a safe design. I can see a lot of slaves in this woodpile. link

The stress optimized designs are certainly weird looking. I've not seen any in practical use, that bicycle part looks like it would be an 'interesting' test.
Of course in an engineering design required strength is calculated, then a safety factor applied, cost and weight are minimized to provide this level of strength. Light weighting is a big deal in automotive design currently, reducing weight to help meet fuel efficiency standards. |

You 3D print an exact duplicate part. Takes 5 minutes!

I think that automobile frame would take a lot more than 5 minutes, even if repair shops had the capability. Of course it's a copy righted part so it would take awhile to do the paperwork and pay the royalties.

That is exactly my worry, the machine designs and builds according to the ethics/goals set by whomever controls the input.

Do the pressure points line up? Looks to me like the shoulder area is under padded, assuming the head area is closest to us. |

Who remains motionless during their sleep? When backpacking, how often do you find yourself sleeping on flat ground without sticks, roots, stones, peas, and god knows what poking up from the ground? Even a small root would easily protrude beyond the thickness of the mat though one of the openings. Seriously, people need to get the fuck off their devices, stop playing with solidworks, sketchup, and autocad and go outside and actually touch the physical world.

But it works fine on top of my mattress.

And would it fit in a "child sized" soda cup? @ 48 sec

I find it intriguing how differently learning is handled by different "students". A group of scientists taught a group of captive-raised monkeys the concept of money by getting them to associate desired behavior with the reward of a small metal circle, which they could then put in a specifically designed vending machine for whatever food treat (visible through windows) they were in the mood for.
Not long after, they noticed something. Male monkeys were performing--and even over-performing--the desired behaviors. Upon getting their "coin", they'd either get a food treat or just hand the "coin" over to a female, who would then reward the male with sex. Yup, we taught monkeys about money and the FIRST thing they invented was sex for hire. Now we teach a computer about stresses and physics and calculus and all that goes into this kind of research, and the stress-optimized designs it comes up with all look vaguely biological. That last photo, the piece that looks like it should clip together, reminds me a LOT of the structure of bird bones, which have just about the best stress-for-weight ratio found above the benthic zones of the oceans. If the current political administration hadn't just gutted every bit of scientific funding (even NOAA lost a massive chunk of its budget...good luck directing your military without weather satellites!) I'd be a lot more excited about the immediate future of this kind of research. |
