Artificial Intelligence to detect suicidal tendency

in #science6 years ago (edited)

A controversial study: in one test an artificial intelligence system was trained to identify psychiatric patients with suicidal tendencies

Artificial intelligence could help identify people with suicidal tendencies, to stop them before they can harm themselves as a result of discomfort. The researchers in Carnegie Mellon University (USA) affirm this in a controversial study. They have put in place the most advanced systems of machine learning and image recognition to predict the intentions of those who are overwhelmed by a malaise and want to end their lives .
The Marcel Just team conducted the study of 17 adult patients with proven suicidal tendencies, starting with magnetic resonance imaging (Magnetic Resonance Imaging, MRI) of volunteer brains.

SUICIDE ANNOUNCED

During MRI, the volunteers, eight of whom had already tried to take their own lives, were stimulated with negative words, such as "despair" or "loneliness", positive words (for example "carelessness") and generically complex words ("problems ").

The researchers then isolated the brain areas activated by the various terms and compared them with those activated by the same words on a neurotypical control group, ie without suicidal tendencies.
The images were used to train a machine learning system expert in photographic analysis and recognition: at the end of the process the computer was able to identify with a precision of 91% the patients who showed self-injurious tendencies.
In a second test, the same system, trained only with images of psychiatric patients, managed to correctly identify those who had already attempted suicide in 94% of cases. The most accurate answers are those related to imaging induced in response to the terms "death", "lifeless" and "carefree".


The study was carried out on a small sample and, to be admitted by the same researchers, should be validated on a much higher number of cases before being able to make a diagnostic tool.

However, the research did not fail to arouse perplexity. Several scientists have declared themselves skeptical about the possibility of using such solutions in everyday clinical practice.

"We need very sophisticated and expensive equipment, but also extremely collaborative patients", says Derek Hill (University College, London).

"Each of our behavior has a biological basis, but it is not said that MRI is the right tool to identify it," says Blake Richards (University of Toronto).

To answer at least in part the objections to technology, the Carnegie Mellon team is trying to repeat the same experiment using a common electroencephalogram, which can be done with simpler, portable and less expensive tools.

Thank you for this dangerous information. It is time to change from the mind to the heart!! The AI will take control over your thoughts if not protected by your hearts magnetic field as it is 5000 times stronger. It is time to make the change the change for saving humanity that start by you!! @beingbeatitude

woow, thank for sharing artificial intelligence, good information

owever, the model can only gage patients’responses to stimuli — it is not foolproof. If patients want to conceal information or give wrong responses, they can still do that, which would affect the accuracy of the algorithm. But it is expected to map brain activity properly and provide an accuracy in detection in many cases that could have been surpassed by clinical psychologists.

AI are going to be a threat to employment in the first place and whenever you give AI full control over actions and thinking in society Hollywood will become reality.

Thank you for this post! Even though it's a controversial study, it's food for our brains. AI's advance is inevitable and it's a matter of time this and other experiments to be backed up with evidence and success.

Very soon AI will detect human feelings also...:D
