Machine learning may help identify ideal dementia treatments

Health
Oct. 22 (UPI) -- Machine learning may someday allow physicians to prescribe the best treatment for dementia, according to a study. Researchers devised and applied a new algorithm that can spot different patterns of progression in patients with a range of dementias in MRI scans, including Alzheimer's disease. The findings were published this month in the journal Nature Communications. "This new algorithm has the unique ability to reveal groups of patients with different variants of disease," Dr. Daniel Alexander, a professor in the University College London Center for Medical Image computing, said in a press release. "One key reason for the failure of drug trials in Alzheimer's disease is the broad mixture of very different patients they test; a treatment with a strong effect on a particul...
Machine learning could help regulators identify environmental violations

Machine learning could help regulators identify environmental violations

Science
Oct. 1 (UPI) -- Regulatory agencies tasked with protecting environmental and public health are regularly understaffed and underfunded, but new research suggests machine learning could help officials more effectively monitor potential violators. The Environmental Protection Agency and partnering state agencies are responsible for monitoring the regulatory compliance of 300,000 facilities. Regulators, however, only have the resources to inspect less than 10 percent of those facilities each year. To help the EPA catch violations, student researchers at Stanford University designed a model to identify facilities most likely to fail an inspection. Scientists trained the machine learning to interpret a variety of risk factors, including the facility's location, industry and inspection history. ...
Learning People attracts new backing from Talis

Learning People attracts new backing from Talis

Business
One of London's leading backers of technology start-ups is leading a multimillion pound investment in Learning People, an online training company which its backers believes is well-placed to capitalise on the explosion in corporate demand for cybersecurity advice. Sky News understands that Talis Capital, which is a shareholder‎ in businesses including Darktrace and Iwoca, will announce this week a fresh commitment to Learning People.‎The online training‎ group and its subsidiary, Skillsfox, will also unveil the appointment to their advisory boards of Tony Glass, former boss of the European operations of Skillsoft, a similar company sold to the buyout firm Charterhouse for $ 2bn‎.‎Talis's new backing for Learning People will follow an initial in...

Chasing quakes with machine learning

Science
Scientists have used machine learning to calculate the pattern of aftershocks following an earthquake.Aftershocks are further quakes that follow the "main shock". They are by definition smaller, but sometimes not by much.This is the first time a machine learning method has been used to work out where they might happen.Researchers hope this and similar techniques will improve our understanding of earthquake behaviour."If you think about making forecasts of earthquakes," says study co-author Prof Brendan Meade of Harvard University, "you want to do three things; you want to predict when they're going to be, you want to say something about how large they're going to be and about where they're going to be."What we wanted to do is to tackle the last leg of thi...
Machine learning can predict low blood pressure during surgery

Machine learning can predict low blood pressure during surgery

Health
June 11 (UPI) -- A new algorithm can predict potentially dangerous low blood pressure during surgery. Researchers have developed machine learning than can identify hypotension as much as 15 minutes before it occurs, and are correct about 84 percent of the time. The findings were published Monday in the journal Anesthesiology. "Physicians haven't had a way to predict hypotension during surgery, so they have to be reactive, and treat it immediately without any prior warning," Dr. Maxime Cannesson, a professor of anesthesiology at UCLA Medical Center in Los Angeles, said in a press release. "Being able to predict hypotension would allow physicians to be proactive instead of reactive." Canesson said the tool can save lives -- even with a warning only 10 to 15 minutes ahead of time. "By findi...
