Scientists in the US are developing artificial intelligence (AI) systems that could help robots assist soldiers in the battlefield in future.
For the research, published in the journal Science Advances, the team looked at soldier brain activity during specific tasks for ways to incorporate AI teaming to dynamically complete tasks.
According to Jean Vettel, a senior neuroscientist at the Army Research Laboratory (ARL) in the US, technologies that can predict states and behaviours of the individual soldier may help create a more optimised team.
“In military operations, soldiers perform multiple tasks at once. They’re analysing information from multiple sources, navigating environments while simultaneously assessing threats, sharing situational awareness, and communicating with a distributed team,” said Vettel.
“This requires soldiers to constantly switch among these tasks, which means that the brain is also rapidly shifting among the different brain regions needed for these different tasks,” he said.
To achieve this future capability, the researchers first sought to understand how the brain coordinates its different regions while executing a particular task. They used a computational approach to understand how this may be characterised to inform the behavioural prediction.
To complete the study, researchers mapped how different regions of the brain were connected to one another in 30 different people via tracts of tissue called white matter.
Scientists converted these maps into computational models of each subject’s brain, and used computers to simulate what would happen when a single region of a person’s brain was stimulated.
“If we can use brain data in the moment to indicate what task they’re doing, AI could dynamically respond and adapt to assist the Soldier in completing the task,” he added.
