Structured exploration enables biological brains to learn more quickly than AI

Researchers at the Sainsbury Wellcome Centre and Gatsby Computational Neuroscience Unit at UCL found the instinctual exploratory runs that animals carry out are not random. These purposeful actions allow mice to learn a map of the world efficiently. The study, published today in Neuron, describes how neuroscientists tested their hypothesis that the specific exploratory actions that animals undertake, such as darting quickly towards objects, are important in helping them learn how to navigate their environment.

AI may predict Alzheimer's five years in advance

Researchers from the University of Toronto in Canada designed an algorithm that learns signatures from magnetic resonance imaging (MRI), genetics, and clinical data. According to the study, the algorithm can help predict whether an individual's cognitive faculties are likely to deteriorate towards Alzheimer's in the next five years.
