Machine learning can help slow down future pandemics

In the study, the researchers developed a method to improve testing strategies during epidemic outbreaks and with relatively limited information be able to predict which individuals offer the best potential for testing. "This can be a first step towards society gaining better control of future major outbreaks and reduce the need to shutdown society," says Laura Natali, a doctoral student in physics at the University of Gothenburg and the lead author of the published study. Machine learning is a type of artificial intelligence and can be described as a mathematical model where computers are trained to learn to see connections and solve problems using different data sets. The researchers used machine learning in a simulation of an epidemic outbreak, where information about the first confirmed cases was used to estimate infections in the rest of the population. Data about the infected individual's network of contacts and other information was used: who they have been in close contact with, where and for how long.
