Scientists have begun using the power of machine learning to decipher messages throughout the animal kingdom.

With the help of modern technology, scientists have already developed an algorithm that analyzes the grunt of a pig to determine whether the animal is experiencing positive or negative emotions. A system called DeepSqueak uses ultrasonic signals to determine if rodents are stressed, and Project CETI plans to use machine learning to translate messages from sperm whales. The Earth Species Project team hopes to decipher non-human communication using machine learning - and make this know-how available to the public. The ESP approach is unique in that it focuses not on deciphering one kind of communication, but all at once.
