AI-based speech pattern analysis may allow Alzheimer's diagnosis by phone

#artificialintelligence

Patterns of speech in a phone conservation can be used to correctly identify adults in the early stages of Alzheimer's disease, a study published Wednesday by the journal PLOS found. Using more than 1,600 voice recordings of phone conversations made from 24 people with confirmed Alzheimer's and 99 healthy controls, researchers correctly identified those with the common form of dementia with roughly 90% accuracy, the data showed. The approach relies on the tendency of people with Alzheimer's "to speak more slowly and with longer pauses and to spend more time finding the correct word," the researchers said. These "vocal features" result in "broken messages and lack of speech fluency," which can be analyzed using an artificial intelligence-based program. The computer program was able to identify those with early Alzheimer's with essentially the same level of accuracy as a telephone-based test for cognitive function, according to the researchers.


Doctors Are Very Worried About Medical AI That Predicts Race

To conclude, our study showed that medical AI systems can easily learn to recognise self-reported racial identity from medical images, and that this capability is extremely difficult to isolate,


Turning off facial recognition can help reduce screen time, study says

Daily Mail - Science & tech

If you spend too much time on your smartphone, scientists have a list of 10 solutions that can help you cut back on screen time. The small but effective changes can help curb smartphone addiction and mental health issues such as depression, say experts at McGill University in Canada. In experiments, people following the strategies reduced their screen time, felt less addicted to their phone and improved their sleep quality, the experts report. Among the 10 strategies are changing the phone display to'greyscale' so the display appears black and white, and disabling facial recognition as a method of unlocking the screen. A black and white screen makes smartphones'less gratifying' to look at compared to the bright colours offered by app icons such as TikTok and Instagram.


AI is better at hiring staff than human bosses, study finds

Daily Mail - Science & tech

Artificial intelligence (AI) is better at hiring staff than human bosses, but companies still don't trust it in the recruitment process, a new study finds. Researchers in London have conducted a review of previous studies that assessed the effectiveness of AI as a recruitment tool. They found AI is'equal to or better than' human recruiters when it comes to hiring people who go on to perform well at work. Although AI had limited abilities in predicting employee outcomes after they were hired, AI is'fairer' and marked a substantial improvement over humans, they reveal. AI also boosts the'fill-rate' for open positions and is'mostly better than humans' at improving diversity in the workplace.


Playing video games can help boost children's intelligence - unlike watching TV!

Daily Mail - Science & tech

Many parents feel guilty when their children spend hours on end staring at screens – and some even worry it could make them less clever. But a new study suggests that spending an above-average time playing video games can actually help boost children's intelligence. Researchers from the Karolinska Institutet in Sweden carried out psychological tests on more than 5,000 children in the US aged between ten and 12, to gauge their general cognitive abilities. The children and their parents were also asked about how much time the children spent watching TV and videos, playing video games and engaging with social media. The researchers then followed up with the children two years later, at which point they were asked to repeat the psychological tests.


Researchers use AI to prompt older adults' participation in research

#artificialintelligence

In a new study, Florida State University researchers explore the challenges of recruiting and retaining older adults to participate in research. The study also marks the first step of a broad, interdisciplinary FSU effort to increasingly use artificial intelligence in research. In the study, published in The Gerontologist, Associate Professor of Sociology Dawn Carr identified core "motivation clusters" among older adults for research participation. Along with her 12 FSU-based co-authors, Carr suggests that identifying those clusters--"fun seekers" and "research helpers," for example--can guide recruitment and retention strategies. "There is a lack of representation of older adults in research that leads to findings that are skewed," Carr said.


Artificial Intelligence Computing Using Networks of Tiny Nanomagnets

#artificialintelligence

Researchers have demonstrated that artificial intelligence may be performed using small nanomagnets that interact like neurons in the brain. Researchers have shown it is possible to perform artificial intelligence using tiny nanomagnets that interact like neurons in the brain. The new technology, developed by a team led by Imperial College London researchers, could significantly reduce the energy cost of artificial intelligence (AI), which is currently doubling globally every 3.5 months. In a paper published today (May 5, 2022) in the journal Nature Nanotechnology, the international team has produced the first proof that networks of nanomagnets can be used to perform AI-like processing. The researchers showed nanomagnets can be used for'time-series prediction' tasks, such as predicting and regulating insulin levels in diabetic patients.


Predict Ads Click - Practice Data Analysis and Logistic Regression Prediction - Projects Based Learning

#artificialintelligence

In this project we will be working with a data set, indicating whether or not a particular internet user clicked on an Advertisement. We will try to create a model that will predict whether or not they will click on an ad based off the features of that user. Welcome to this project on predict Ads Click in Apache Spark Machine Learning using Databricks platform community edition server which allows you to execute your spark code, free of cost on their server just by registering through email id. In this project, we explore Apache Spark and Machine Learning on the Databricks platform. I am a firm believer that the best way to learn is by doing.


Covid lockdown made people more creative, study says

Daily Mail - Science & tech

Whether it was doing the kitting or learning to play a new instrument, the Covid lockdown made people more creative, a new study says. Researchers in Paris have surveyed hundreds of people about activities performed during the first lockdown at the start of the pandemic more than two years ago. Overall, based on almost 400 responses, the team found that people were forced to adapt to a new situation and'rethink our habits', which bred creativity. The researchers also acknowledged that pandemic and stay-at-home rules'restricted our liberties and triggered health or psychological difficulties', however. The new study has been led by researchers from the Frontlab at the Paris Brain Institute in France and published in Frontiers in Psychology.
