8. Machine learning radically reduces workload of cell counting for disease diagnosisПт, 20 мая[-/+]
Категория(?)  
The use of machine learning to perform blood cell counts for diagnosis of disease instead of expensive and often less accurate cell analyzer machines has nevertheless been very labor-intensive as it takes an enormous amount of manual annotation work by humans in the training of the machine learning model. However, researchers at Benihang University have developed a new training method that automates much of this activity.

17. New brain-painting method being tested for ADHD treatmentПт, 20 мая[-/+]
Категория(?)  
Imagine focusing on one thing so well that you can control its movement. Now, imagine mentally selecting colors and shapes to create an abstract image—a brain painting. USF computer scientist Marvin Andujar is harnessing the power of concentration and art to develop a new brain-computer interface (BCI) prototype and help study participants use their brain like never before. The goal is to introduce a novel treatment option for individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) by tapping directly into their brain activity.

Категория(?)  
Do you spend more time on your smartphone than you would like and have trouble cutting back your screen time? You are not alone. McGill University researchers may have found a solution based on "nudges," small changes to phone settings or behavior that can help curb smartphone addiction. The intervention includes various components such as changing the phone display to greyscale and keeping the phone out of the bedroom when sleeping. The researchers found that participants following the intervention reduced their screen time, reported feeling less addicted to their phones, and had better sleep quality.
