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.

>The data is supposed to show
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.
Do you guys support nuclear energy? Why/why not?
>>7898319
No, it's retarded.
nuclear is the future
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 are some proofs on why only the third one of the seen subsets of R^3 is viable?
Why does it have to be parabolic?
>>7898189
Learn how to communicate and then come back
>>7898189
define 'viable'
>>7898194
I think he's asking why asymptotes have to be parabolic
How the fuck do you define the natural numbers?
all non negative integers

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.

What are some 'safe' painkillers?
>>7897711
I've heard some people cut their arms to kill the pain of existence.
Pretty safe if you do it right.
None and any.
Vague questions get vague answers.
Opioids and opiates
Gotta write a 6 page essay about the socio-economic impact AI will have.
Does /Sci/ any useful thoughts, insights or opinions?
>>7897084
does is matter? when the AI takes over, that paper isn't gonna mean shit to a logical, utilitarian mind set to make the world efficient.
>>7897084
AI won't ever happen. It's a singularityfag pipe dream.
>>7897084
All the power and money will go to the owner of the AIs, meanwhile most of the population won't be able to sell their subpar labour at competitive prices.
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? 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?

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....

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...

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...

[MODEL] Initially I want to go with boosted trees because its the easiest to implement. And because adding classifiers and branching criteria can happen over time without heavily impacting performance.

[Data Collection] I'm thinking about running a 4chan and Reddit downloader exclusively SFW sections of 4chan and Reddit to produce a control categories the running the rest on the Exclusively NSFW sections.
Gifs and webms can either be disregarded or completely decomposed.into separate frames and added to our dataset.

deary me, I guess I'll have to corrupt your training data then

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?
Take loans
Crippling debt.

How long until we colonize Mars?
>>7896105
Never. There's no reason to.
>>7896105
I doubt it will ever happen. The people who believe that colonization on Mars is achievable are probably the biggest optimists that've ever lived.

You've clearly never been to a hood haven't you?
Hey /sci/,
What are the best /sci/-fi Books? Which ones have you read and how did you like them?
For me:
>Solaris - Stanislaw Lem (excellent)
>Asimov - I, Robot (neat)
Manifold Series Stephen Baxter
Alastair Reynolds Revelation Universe
Greg Egan-if you want really heavy SF
Peter Watts
Gregory Benford
Most PKD books.

>tfw invasive species are becoming more and more of a problem
>tfw 6th global extinction is in sight
How do we effectively kill invasive species /sci/?
pic related: the asian ladybug. Introduced in American and Europe in the '50s and is now the main ladybug species there. Native ladybug populations have fallen dramatically because of this
>>7894252
I know you're trolling on the /pol/ part, but invasive species are a threat to the global biodiversity. Science can learn a lot from nature, but at this rate there won't be any special or interesting species left in the future
If /sci/ knew the answer invasive species wouldn't be a problem
I've read it across various boards, but never really got it. Why is compsci seen as a meme? The curriculum is definitely easier than say math or physics, but some claim that the whole discipline is a joke and stopped developing significantly since the '70-'80's or something. And they scoff whenever there is a mention of
>compsci
with their anime reaction gif.
Can some1 give a serious explanation of this meme?
>>7894043
Because if you study engineering, you become a superior being

Shouldnt software engineering gain the respect of other engineering disciplines?
Ideally your shit comes out as a smooth, single turd that barely requires wiping at all. But how many people consistently have good poop like this? How do start taking shits like that, what to eat etc? How doable is this still in this age?
Just eat a lot of fiber from various sources.
just eat lots of fiber and drink lots of water.

I use like one roll of TP per shitting session. I think this is the cause for my shitposting.
