Algorithm Can Identify Suicidal People Using Brain Scans (wired.com)
An anonymous reader quotes a report from WIRED: In a study published today in Nature Human Behavior, researchers at Carnegie Mellon and the University of Pittsburgh analyzed how suicidal individuals think and feel differently about life and death, by looking at patterns of how their brains light up in an fMRI machine. Then they trained a machine learning algorithm to isolate those signals -- a frontal lobe flare at the mention of the word "death," for example. The computational classifier was able to pick out the suicidal ideators with more than 90 percent accuracy (Warning: source may be paywalled; alternative source). Furthermore, it was able to distinguish people who had actually attempted self-harm from those who had only thought about it. In today's study, the researchers started with 17 young adults between the ages of 18 and 30 who had recently reported suicidal ideation to their therapists. Then they recruited 17 neurotypical control participants and put them each inside an fMRI scanner. While inside the tube, subjects saw a random series of 30 words. Ten were generally positive, 10 were generally negative, and 10 were specifically associated with death and suicide. Then researchers asked the subjects to think about each word for three seconds as it showed up on a screen in front of them. "What does 'trouble' mean for you?" "What about 'carefree,' what's the key concept there?" For each word, the researchers recorded the subjects' cerebral blood flow to find out which parts of their brains seemed to be at work.
Did these people even try suicide? Does suicide-thought even = suicidal?
And the rest of the GOP.
They've invented political affiliation detection, education level detection, eGaydar, and now suicide detection. What's next, fingerprints that indicate one jacks off twice a day...I mean once a day?

I hope this algorithm will help prevent suicides.
However, the increasing ability of machines to read minds is getting a little scary. Some day we'll be able to read someone's emotions without hooking the person up to a machine - just point a reader at their head.
Government employee: What do you think of our dear leader?
The person's brain shows the emotion of revulsion.
Government employee: Off to a re-education camp, for you and your family!
Completely scary that mind reading is about to become mainstream. Lie detector tests are going to seem quaint very soon.

“He gazed up at the enormous face. Forty years it had taken him to learn what kind of smile was hidden beneath the dark moustache. O cruel, needless misunderstanding! O stubborn, self-willed exile from the loving breast! Two gin-scented tears trickled down the sides of his nose. But it was all right, everything was all right, the struggle was finished. He had won the victory over himself. He loved Big Brother”

Maybe not, but the ironically named "Anti-FA" shows a troubling trend. Is it too late to defeat?
Just 17 samples to train a classifier on some 10^N inputs (where N > 3, 6, 9, more?!?!), with > 90% accuracy... muwahahaha, yeah right.
I discovered a way to detect someone's intent to scan my brain.

While the most common reason for suicide is linked to a depressive state, it is not always the case that depression is linked to any ongoing psychological abnormality that could be diagnosed clinically, or that anyone would have a reason to want to do a brain scan on you in the first place over.
In fact, there are some life experiences that, if you didn't experience any kind of depression, and could always completely detach yourself from any emotional investment, then *THAT* would be an indication of something being wrong with you. Losing a beloved family member, sudden unwanted changes in living circumstances, being wrongfully accused of a crime... all of these things and more can be legitimate reasons for a depressive state that can turn suicidal.
But such depression is entirely circumstantial, and not indicative of a larger scale psychological dysfunction... and because of its ephemeral nature, would not generally be caught on anything like a brain scan.
While the theory for this might seem wonderful, I have serious doubts it would actually ever save anyone's life.

So anyone can be detained, how does one proved their thoughts are pure ;)

It's probably a preprint without the last-minute changes, but it should be good enough to understand the research.

So it detects if someone would say they're suicidal vs actually suicidal. It's the wrong training set completely. People who are suicidal commit suicide, they don't sign up to be tested for suicidal thoughts testing. You won't find those people in that training set FFS.
Statistician: "we've found a test for people who will lose weight"... "we scan their brains and then ask them if they want to lose weight and train a neural network to match the two correlates up... it's 90% of perfect detection".
Engineer: "So how many people say they want to lose weight but don't successfully lose weight, and how many people say they *want* to lose weight but never even take the most basic steps at losing weight?"
Statistician: "Did I also mention we used the cloud to store our deep learning results?"
the one's trying to prevent someone to end his/her life are just afraid of their own final destiny in this plane of existence with their body. Won't help them though, it will happen to them. .... . ...

There is so much messing around with one's basic rights - about your body, what you do with whom in your bedroom, what you can speak, what happens to the information about you - do you get compensated if someone uses it or penalized if it's without your explicit permission to make money of it.

You don't need brain scans for this. Databrokers already try to figure this by datamining your data.
Soon it will be possible to classify all loonies, botleys, nutters, psychos, and whackos with a simple scan
Mike Judge, you seer. This is idiocracy in the making.
Then they recruited 17 neurotypical control participants and put them each inside an fMRI scanner. While inside the tube, subjects saw a random series of 30 words. Ten were generally positive, 10 were generally negative, and 10 were specifically associated with death and suicide.
I sure hope no one of any importance in a decision-making position of authority confuses this bullshit with real, legitimate research. Control size was 17. Seventeen controls? How many people are on an professional football team? If you picked 17 people at random, it's easy to get all, or almost all professional football players, and you could extrapolate from that that all, or almost all humans, can play football on a professional level, and all they need is the helmet and pads.
Seventeen is not a large enough sample size for jack or shit. Also, 30 words? Generally negative? Generally positive? According to WHOM? I'll bet for SOME people, the word "Palestinian" is positive, and for some negative. Same for the words "black" and "white". Depends on your point of view, so the 'word list' is garbage... and if only TEN of each group were considered wholly negative or entirely positive...
Yeah, this is bullshit and it's sad if anyone buys into the nonsensical and/or unbelievable drivel. This is gallons and gallons of stew from barely ONE oyster.
Our reign has gone on long enough. Indeed. Summon the meteors.
I'm pretty sure this detector would be making lots of false positive detections when scanning black/death metal fans. Death and suicide are a hot topic in this kind of music. Horror books/movies fans might be affected too.
Now, can you do the same thing with therapist to identy the bads one. If we want good treatments, we need competent therapists.
I assume that people who commit suicide without doing some suicidal ideation first are relatively rare(and likely most common in 'never take me alive!' type scenarios, not standard mental health practice); but this thing seems totally useless if what it detects is mere suicidal ideation, rather than actually picking out the differences between people who think they would be better off dead and the ones who go through with it.
Especially given that depression tends to ruin your focus, motivation, and ability to execute a plan (even one you fully agree would be in your interests); people who would merely prefer to be dead are a larger group, likely by a fair margin, than ones who do something about it. If all your fancy brain scan can do is provide the same 'are you thinking about suicide?' data that a few minutes of sympathetic questioning by a vaguely competent counselor or psychologist can, it is a scientific curiosity. What would actually be interesting is telling us which of the suicidal ideators are justing fantasizing; and which ones are preparing.
(Now, if you really wanted to get futuristic, you could look into having a reasonably efficacious treatment option available for those you identify...)
Slap that algol shit on progressive sluts. Watch 'em die like lemmings in the collapsing Trotsky wavefunction ... oooh da BooBoo .... bakkk da BadBad ... doncha hate it when Rawlsian bitches pump-da-shark , Weinsteining sex and go screaming into the night ?
It is easy to explain the suicidal nature of bees and ants. They are genetically identical to their queen, who is their sister. So any child of the queen is the child of the worker, so she (all workers are females) is willing to die for her queen.
In some sense an insect colony is a distributed individual. A worker defending her colony suicidally is same as a porcupine willing to lose quills in defense.
But, a mammal, primate like us still having suicidal thoughts in our gene pool is inexplicable.
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
Might as well point a dowsing rod at people, or have a panel of self-described experts look for "tells" not unlike a gaggle of highschoolers.
Scary? It's the desired, realized wet dream!
All I wanted was a pepsi
It would have to be a group of people who participated in a suicide study and died under mysterious conditions made to look like suicide.

Artificial Intelligence Can Now Predict Suicide With Remarkable Accuracy — 16 June 2017
All we need now is an algorithm capable of picking out Winona Ryder (as goth-girl Lydia) from a Beetlejuice police line-up, and that about wraps it up for suicide prediction.
Pattern classification, as used in this study, is not neural mind-reading. Here's a good article by a neuroscientist that explains how it actually works -- and its limitations -- in plain English.
Pattern Classification Explained
I invented a cheaper machine. It doesn't need to scan your brain, it just needs to know your age. If you're under thirty, it will guess yes and be right most of the time.
I fail to see the practical use of this. It's not like we regularly brain scan people.
Look, MRI scans are expensive. Interpreting them is even more expensive.
Even the cheapest headset MRI scans run 3-4 figures.
So, in terms of detection, lack of availability, and even having such scans be useful, this is just not going to change anything.

Fake brain scans so they can put anyone that's not part of the nwo establishment in mental wards
They confirmed this in an initial experience with suicidal salmon. Not surprised at the human results.
Many neurologists & psychiatrists have told me that "seeing" mental health disorders in medical images would revolutionise prevention, diagnosis and care, and aid development of truly effective interventions. Most MRI scanners are supercooled beasts; you need to get architects involved to install one. Maybe we more office-sized MRI machines for specific body parts? Our heads and joints do appear to be wearing out...
