Meet DeepSqueak, an algorithm built to decode ultrasonic rat squeaks

Researchers at the University of Washington recently unveiled a remarkable software tool known as DeepSqueak. The program can automatically identify, process, and sort rat and mouse squeaks. It might seem whimsical, but knowing what rodents are squeaking about could be extremely valuable to animal researchers.

Mice and rats are foundational to modern medical science. By one tally, mouse and rat studies have earned around 75 Nobel Prizes in health and physiology. Rats, in particular, are smart and communicative, and understanding their communication could add a useful data layer to countless studies. If a rat avoids tasty sugar water in an experiment, for example, is it demurring because it’s happily distracted or because it’s too…
