Audio recordings from the evaluations were transcribed and manually annotated.Researchers evaluated 103 teenage students in 74 traditional schools throughout the US who had a major or minor behavioural change or aggression toward themselves or others. That is our next goal," said Barzman, lead author of the study published in the journal Psychiatric Quarterly."Our ultimate goal, should research support it, is to spread the use of the machine learning technology to schools in the future to augment structures, professional judgment to more efficiently and effectively prevent school violence," said Barzman.

"Previous violent behaviour, impulsivity, school problems and negative attitudes were correlated with risk to others," said Drew Barzman, a child forensic psychiatrist at Cincinnati China coaxial cables Suppliers Childrens Hospital Medical Center in the US. The machine learning algorithm that the researchers developed achieved an accuracy rate of 91. We did not gather outcome data to assess whether machine learning could actually help prevent school violence."Our risk assessments were focused on predicting any type of physical aggression at school.45 per cent when demographic and socioeconomic data were added.

The team performed school risk evaluations with participants."The machine learning algorithm, based only on the participants interview, was almost as accurate in assessing risk levels as a full assessment by our research team, including gathering information from parents and the school, a review of records when available, and scoring on the two scales we developed," said Yizhao Ni, a computational scientist at Cincinnati.02 per cent, considered excellent, when using interview content to predict risk of school violence.There were significant differences in total scores between the high-risk and low-risk groups.

The researchers found that machine learning—the science of getting computers to learn over time without human intervention—is as accurate as a team of child and adolescent psychiatrists, including a forensic psychiatrist, in determining risk for school violence. The students, as it turned out, were relatively equally divided between moderate- to high-risk, and low-risk, according to two scales that the team developed and validated in previous research.Scientists have developed an artificial intelligence system that can help predict which students are at higher risk of perpetrating school violence.The students were recruited from psychiatry outpatient clinics, inpatient units and emergency departments.The rate increased to 91
