Autism


La veille de la cybersécurité

#artificialintelligence

According to observations, children with autism frequently speak more slowly than similarly developing kids. They differ in their speech in other ways, most notably in tone, intonation, and rhythm. It is very challenging to consistently and objectively describe these "prosodic" distinctions, and it has been decades since their roots have been identified. Researchers from Northwestern University and Hong Kong collaborated on a study to shed light on the causes and diagnoses of this illness. This method uses machine learning to find speech patterns in autistic children that are similar in Cantonese and English.

AI Detects Autism Speech Patterns Across Different Languages - AI Summary

#artificialintelligence

Summary: Machine learning algorithms help researchers identify speech patterns in children on the autism spectrum that are consistent between different languages. The data used to train the algorithm were recordings of English- and Cantonese-speaking young people with and without autism telling their own version of the story depicted in a wordless children's picture book called "Frog, Where Are You?" "Using this method, we were able to identify features of speech that can predict the diagnosis of autism," said Lau, a postdoctoral researcher working with Losh in the Roxelyn and Richard Pepper Department of Communication Sciences and Disorders at Northwestern. Finally, the results of the study could inform efforts to identify and understand the role of specific genes and brain processing mechanisms implicated in genetic susceptibility to autism, the authors said. Using a supervised machine-learning analytic approach, we examined acoustic features relevant to rhythmic and intonational aspects of prosody derived from narrative samples elicited in English and Cantonese, two typologically and prosodically distinct languages. Summary: Machine learning algorithms help researchers identify speech patterns in children on the autism spectrum that are consistent between different languages.

#artificialintelligence

A new study led by Northwestern University researchers used machine learning--a branch of artificial intelligence--to identify speech patterns in children with autism that were consistent between English and Cantonese, suggesting that features of speech might be a useful tool for diagnosing the condition. Undertaken with collaborators in Hong Kong, the study yielded insights that could help scientists distinguish between genetic and environmental factors shaping the communication abilities of people with autism, potentially helping them learn more about the origin of the condition and develop new therapies.

Undertaken with collaborators in Hong Kong, the study yielded insights that could help scientists distinguish between genetic and environmental factors shaping the communication abilities of people with autism, potentially helping them learn more about the origin of the condition and develop new therapies. Children with autism often talk more slowly than typically developing children, and exhibit other differences in pitch, intonation and rhythm. But those differences (called "prosodic differences'" by researchers) have been surprisingly difficult to characterize in a consistent, objective way, and their origins have remained unclear for decades. However, a team of researchers led by Northwestern scientists Molly Losh and Joseph C.Y. Lau, along with Hong Kong-based collaborator Patrick Wong and his team, successfully used supervised machine learning to identify speech differences associated with autism.


Bot Discovers Why Some Autistic Adults Can't Detect Emotion

#artificialintelligence

One common symptom that people with autism struggle with is the inability to interpret facial expressions. This can lead to difficulty in reading social cues in their personal lives, school, workplace, and even media like movies and TV shows. However, researchers at MIT have created an AI that helped shed light on why exactly this is. A paper published on Wednesday in The Journal of Neuroscience unveiled research that found that neurotypical adults (those not displaying autistic characteristics) and adults with autism might have key differences in a region of their brain called the IT cortex. These differences could determine whether or not they can detect emotions via facial expressions.

Artificial neural networks model face processing in autism

#artificialintelligence

Many of us easily recognize emotions expressed in others' faces. A smile may mean happiness, while a frown may indicate anger. Autistic people often have a more difficult time with this task. But new research, published June 15 in The Journal of Neuroscience, sheds light on the inner workings of the brain to suggest an answer. And it does so using a tool that opens new pathways to modeling the computation in our heads: artificial intelligence.

AI Device Helps Diagnose Autism in Children

#artificialintelligence

A new peer-reviewed study published in npj Digital Medicine, a Nature Portfolio journal, shows the results of a clinical trial in which an artificial intelligence (AI) machine learning Software as a Medical Device (SaMD) helped primary care providers assess whether young children have autism spectrum disorder (ASD). Autism is a whole-body disorder with common co-morbidities that include anxiety, depression, attention deficit and hyperactivity disorder (ADHD), schizophrenia, bipolar disorder, sleep disturbances, gastrointestinal disorders, eating and feeding issues, and seizures. Autism affects all ethnic groups, and boys are four times more likely to be diagnosed with autism than girls. The World Health Organization (WHO) estimates that one in 100 children globally has autism spectrum disorders. Approximately one out of every 44 American eight-year-old children were identified with autism in 2018 according to the Autism and Developmental Disabilities Monitoring (ADDM) Network of the U.S. Centers for Disease Control and Prevention (CDC).
