Artificial intelligence learns 'song' of coral reefs

England: According to new research, artificial intelligence (AI) can track the health of coral reefs by learning the "song of the reef." The research has been published in the journal, "Ecological Indicators". Coral reefs have a complex soundscape – and even experts have to conduct painstaking analyses to measure reef health based on sound recordings. In the study, University of Exeter scientists trained a computer algorithm using multiple recordings of healthy and degraded reefs, allowing the machine to learn the difference. The computer then analysed a host of new recordings, and successfully identified reef health 92 per cent of the time.
