Machine learning—also for the bats

Neuroecologist, Yossi Yovel and his team modified a machine learning algorithm, so they could analyze how Egyptian fruit bats communicate. The result? Bats speak to each other as individuals—and actually communicate specific problems. This is breakthrough research in our understanding of how animals communicate. From Jason Daley’s Smithsonian article: “They were able to classify 60 percent of the calls into four categories. One of the call types indicates the bats are arguing about food. Another indicates a dispute about their positions within the sleeping cluster. A third call is reserved for males making unwanted mating advances and the fourth happens when a bat argues with another bat sitting too close. In fact, the bats make slightly different versions of the calls when speaking to different individuals within the group, similar to a human using a different tone of voice when talking to different people.” READ THE FULL ARTICLE.
