Let's just assume one has acquired the fundamentals of logic at around age 12(ish)

Aside from mathematics, does logic exist aside from emotion? For example, don't we exist for emotion? Haven't we evolved through emotion rather than from emotion? I've heard it said that da Vinci had no emotion, but can you really make art without it?

What do you think, /sci/?

what makes you think that soon

Does this line look like a good fit?

The data points are the attractiveness ratings of the voices of women aged 18-55. The data is supposed to show that women's voices are at their most attractive at about 26 but the data points are all over the place. We also don't know how voices under 18 would be rated and this could change the best fit line a lot.

no the data isn't supposed to show anything.
you're trying to make it show something, and you can always transform the data to make it show what you want.
I really hope you never publish anything

>>7899232
It looks reasonable, you could do Graphical Residual Analysis to check, but I think that only works for linear fits, if that's the case would it matter much if you did a semi-log or log-log plot?

what about you make the diagram start at 18 instead of 10

I dont come here often. Frankly I dont know very much about science. But I am curious on an opinion from this board. Explanations will be appreciated.

Ain't it funny how the libs blather about oil/coal money when it comes to global warming, then ignoring the reality that fossil fuels is behind the anti-nuclear movement
>>
>>7898323
Most reactor waste piles up with no where to go and the rest comes out the barrels of guns, not to mention the primary objective of the science - building really big bombs.

Most ignoramus like yourself assume no fossil fuels are used to mine, refine and move the product to the reactors built with massive amounts of fossil fuels themselves. Besides, there are already enough reactors to consume most of the radioactive rock left worth mining now.

What's /sci/'s opinion on the wild burger? Any research mathematicians here that can shed some light on whether what this guy says is bullshit or not? Is modern mathematics fundamentally flawed? Was set theory the worst thing to happen to math?

Yes most of what he says is bullshit. He's the equivalent of that 0.001% of climate scientists who think man-made climate change isn't real.
>>
He is full of shit. Rationals don’t exist. Only natural numbers (without 0) exist and are axiomatized as numbers of apples in baskets. This is the true purity of purest of pure intellectual mathematics. There are physical implications as well: a length is always a multiple of the Planck length just like a time is always a multiple of the Planck time and a temperature is always a multiple of the Planck temperature.

I was thinking about consciousness the other day and something occurred to me. If consciousness happened during the evolutionary process and is a natural do able thing then shouldn't we in theory be able to make an A.I that has consciousness? Also why haven't we been able to do it yet? or don't we have enough of an understand of our brain and technology to do it yet?

I was thinking about ghosts the other day and something occurred to me. If ghosts happened during the evolutionary process and are a natural do able thing then shouldn't we in theory be able to make an A.I that becomes a ghost?

About a week or two ago there was a couple of threads on /sci/ about what ghosts are, most people were just trolling in them and making fun of OP, telling him to go to /x/, but I got interested in them when some of the posters mentioned some properties of ghosts. Because of this I did some research, got some books and read them and now finally I know what ghosts are! I found out relatively quickly that ghosts are basically fields in space, but you cant really detect them because of how they interact with normal matter. You see, the universe loves symmetries, everywhere you find symmetries in nature, but sometimes these symmetry cause disturbances in reality and cause "unphysical" things to happen that arnt part of our universe and that's why ghosts exist, they balance "unphysical" forces by interacting with the object these "unphysical" forces interact with, canceling the "unphysical" force. This is also why we cant directly see ghosts, they are always in balance with other energy fields. at least thats how "Faddeev-Popov" ghosts work.

We don't have detailed understanding how brain works. There might even be some quantum level phenomenons and no one yet understands quantum physics. One theory is that consciousness is the sum of continuous sensory input. This would allow very low level consciousnesses to exist and could be thought to be in correspondence with different level of animals. I think this model works very well with the evolution and cumulative improvements over time.

I think it is nice theory that makes sense in many ways but it is not perfect. It lacks the concept of the one which chooses. So the theory can't be complete. It is similar to think that the end of the wire bundle would have consciousness just because it is a data endpoint.

But sure man is the living proof that biological machine is possible and that AI is technically possible.

To that other guy, while we can't rule out ghost like behavior from the consciousness before we can tell what consciousness actually is. There is very little to assume it could work without attached to living organism. How do you think that we could have something in our physical world that has no physical form. How something could interact with physics that has no physical parts. What it would be. It would need so large jump in philosophical world that it is just not meaningful. Technically it is not impossible but it is most improbable.

Ok /sci/. Lets talk about nudity detection algorithms and how they work.

Currently, nudity detection seems to center around:
- Detecting skin by color.
- Attempts to detect faces, their size, and comparing it to the size of the skin blob extracted from the photo.
Checking if the size of the skin-blob is the size of a human, if its smaller then the human is probably dressed. If you couldn't find a face or the blob. The algorithm passes on.
-If the image comes from a webpage or other context with some text, scan the text for cues, also consider the source of the image
-Last resort is to try a detection pipeline like rcann to find genitals (why not run it first? Because its expensive (slow), and because it is not nearly as accurate as needed.

This is state of the art nudity detection /sci/ and its bullshit.

I think we can do better. This thread is about figuring out how.

In about two weeks time I'll implement all suggestions in this thread and give you a porn filter(or finder)

Categories for discussion include:
--How to collect training/test data.
--Manual Feature Engineering
--Model selection

If anyone wants to get on board I may even make a slack for a temporary sci working group that can grow into other projects in the future if we mesh well.

hey /sci/ how do you guys afford college?

I went for a year at a state uni for engineering but had to leave due to not being able to afford it. My grades were good but I couldn't get any scholarships. So how do you guys afford your education?
