The algorithm can identify distinct click patterns among millions of clicks made by wild dolphins researchers hope the technology could be used to help distinguish between dolphin species in the wild how does it work the researchers developed an algorithm that can pick out consistent click patterns in very large datasets rather than being taught to recognize patterns that are already.

Known the algorithm is unsupervised and.

Seeks patterns on its own during testing the algorithm was able to identify consistent patterns in a data set of over 50 million clicks recorded in the Gulf of Mexico over a two-year period these click types were consistent across monitoring sites in different.

Regions of the Gulf and one of the click types that emerged is known to be associated with a dolphin species researchers from the Scripps Institution of Oceanography in San Diego build autonomous underwater acoustic sensors that can record dolphins as clicks in the wild for over a year.

At a time these instruments are used to study a range of aspects of dolphin populations including how they are affected by the Deepwater Horizon oil spill natural resource.

Development and climate change but because the sensors record millions of clicks it’s difficult for a human to recognize any species specific patterns in the recordings to overcome this issue the researchers developed an algorithm that can pick out consistent click patterns in very large datasets rather than being taught to recognize.

Patterns that are already known the algorithm is unsupervised and seeks patterns on its own during testing the algorithm was able to identify consistent patterns in a data set of over 50 million clicks recorded in the Gulf of Mexico.

Over a two-year period these quick types were consistent across monitoring sites in different regions of the Gulf and one of the clip types that emerged is known to be associated with a dolphin species dolphins use a process called its allocation to help them identify where objects are located the animal send out clicking noises in the form of sound waves which hit an object and bounce back vibrations.

The amount of time it takes for the sound waves.

To come back helps the dolphins to identify their distance from the object the longer the sound waves the further away the object it.

Also gives them information about the location of the object and some indication of the shape and size of it the researchers now plan to integrate the algorithm with deep learning methods to improve its ability to identify click types dr. Caitlin Fraser lead author of the study said it’s fun to think about how the machine learning algorithms used to suggest music or social media friends to people could be reinterpreted to help with ecological research challenges innovations in sensor technologies have opened the floodgates in terms of data about.
