AI system self-organizes to develop features of brains of complex organisms

Posted by in categories: biotech/medical, robotics/AI

Cambridge scientists have shown that placing physical constraints on an artificially-intelligent system—in much the same way that the human brain has to develop and operate within physical and biological constraints—allows it to develop features of the brains of complex organisms in order to solve tasks.

As such as the organize themselves and make connections, they have to balance competing demands. For example, energy and resources are needed to grow and sustain the network in , while at the same time optimizing the network for . This trade-off shapes all brains within and across species, which may help explain why many brains converge on similar organizational solutions.

Jascha Achterberg, a Gates Scholar from the Medical Research Council Cognition and Brain Sciences Unit (MRC CBSU) at the University of Cambridge said, “Not only is the brain great at solving , it does so while using very little energy. In our new work we show that considering the brain’s problem-solving abilities alongside its goal of spending as few resources as possible can help us understand why brains look like they do.”
