Smarter training of neural networks
Researchers report artificial neural networks contain subnetworks that are considerably smaller, yet capable of being trained to make equally accurate predictions. Many subnetworks can learn to make accurate predictions much faster than the original networks.... Read More...
AI can detect depression in a child’s speech
An auditory-based machine learning algorithm was able to identify children diagnosed with depression and anxiety with 80% accuracy after analyzing recordings of their speech. The algorithm identified eight audio features that signify a higher risk of depression. Of these, a lower pitch of voice, repeatable speech inflections and a higher pitch response to surprise stimuli, were more indicative of depression. Researchers hope to develop a smartphone app that records and analyzes speech immediately, helping to better detect children at risk of internalizing disorders.... Read More...
Dataset bridges human vision and machine learning
BOLD5000, a new, large scale data set of brain scans of people viewing images, is helping researchers to better understand how the brain processes images. The data set is a big step towards using computer visual models to study biological vision.... Read More...
Artificial intelligence reveals what neurons in the visual cortex prefer to look at
A new deep learning algorithm can reliably determine what visual stimuli neurons in the visual cortex respond best to.... Read More...
Artificial neural networks can be used to drive brain activity
Current deep learning models are able to create images strongly enough to activate specific neurons in the visual cortex. However, researchers say more accurate artificial neural network models should be developed to help produce more accurate control.... Read More...
These trippy images were designed by AI to super-stimulate monkey neurons
The XDREAM generative deep neural network utilizes firing rates of neurons in the visual cortex to guide the evolution of a novel, synthetic image. The evolved images activate neurons more than large numbers of natural images.... Read More...
A comprehensive map of how Alzheimer’s affects the brain
Axon myelination is significantly disrupted in patients with Alzheimer's disease. Researchers also found brain cells of men and women vary significantly in how their genes respond to the neurodegenerative disease.... Read More...
Scientists translate brain signals into speech sounds
A neural decoder is able to use sound representations encoded in human cortical activity to synthesize audible speech. The technology could be used to help those with difficulties speaking to communicate freely.... Read More...
Artificial intelligence can diagnose PTSD by analyzing voices
Artificial intelligence technology is able to objectively differentiate between those with PTSD and those without by analyzing speech samples, with 89.1% accuracy.... Read More...
