Washington [US], January 12 (ANI): Computer-based artificial intelligence can function more like human intelligence when programmed to use a much faster technique for learning new objects, say two neuroscientists who designed such a model that was designed to mirror human visual learning.
In the journal Frontiers in Computational Neuroscience, Maximilian Riesenhuber, PhD, professor of neuroscience, at Georgetown University Medical Center, and Joshua Rule, PhD, a postdoctoral scholar at UC Berkeley, explain how the new approach vastly improves the ability of AI software to quickly learn new visual concepts. Our model provides a biologically plausible way for artificial neural networks to learn new visual concepts from a small number of examples, says Riesenhuber. We can get computers to learn much better from few examples by leveraging prior learning in a way that we think mirrors
Study suggests delivering news with humour makes young adults more likely to remember, share ANI | Updated: Jan 10, 2021 11:18 IST
Washington [US], January 10 (ANI): Humour may help keep people informed about politics and other current issues, suggest the findings of new research.
A study from the Annenberg School for Communication at the University of Pennsylvania and the School of Communication at Ohio State University found that, when compared to non-humorous news clips, viewers are not only more likely to share humorously presented news but are also more likely to remember the content from these segments. For democracy to work, it is really important for people to engage with news and politics and to be informed about public affairs, said senior author Emily Falk, Professor of Communication, Psychology, and Marketing at Annenberg.
Cooling vests alleviate perceptual heat strain perceived by COVID-19 nurses ANI | Updated: Jan 10, 2021 08:25 IST
Amsterdam [Netherlands], January 10 (ANI): Wearing cooling vests during a COVID-19 shift ensures that nurses experience less heat during their work, suggests the findings of a novel study.
During their shifts, nurses wear protective clothing for three hours in a row, during which the temperature can rise to as much as 36 degrees. The cooling vests offer such effective cooling that they are now part of the standard work clothing for nurses in the COVID nursing departments at Radboud university medical center. The study was published in the journal Temperature.
Researchers discover music-induced emotions can be predicted from brain scans ANI | Updated: Jan 03, 2021 13:34 IST
Turku [Finland], January 3 (ANI): In a recent study, researchers discovered what type of neural mechanisms are the basis for emotional responses to music.
Altogether 102 research subjects listened to music that evokes emotions while their brain function was scanned with functional magnetic resonance imaging (fMRI). The study was carried out in the national PET Centre.
The researchers used a machine-learning algorithm to map which brain regions are activated when the different music-induced emotions are separated from each other.
- Based on the activation of the auditory and motor cortex, we were able to accurately predict whether the research subject was listening to happy or sad music. The auditory cortex processes the acoustic elements of music, such as rhythm and melody. Activation of the motor cortex, then again, maybe rel
Blood vessel damage, inflammation in COVID-19 patients brains: Study ANI | Updated: Jan 03, 2021 13:50 IST
Washington [US], January 3 (ANI): A team of researchers from National Institutes of Health, in an in-depth study of how COVID-19 affects a patient s brain, have consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples. These damage hallmarks were spotted in patients who died shortly after contracting the disease.
In addition, they saw no signs of SARS-CoV-2 in the tissue samples, suggesting the damage was not caused by a direct viral attack on the brain. The results were published as correspondence in the New England Journal of Medicine.
