AI Distinguishes Birds That Even Experts Can't (sciencemag.org) 32

Slashdot reader sciencehabit quote Science magazine: It's a fact of life for birders that some species are fiendishly difficult to tell apart — in particular, the sparrows and drab songbirds dubbed "little brown jobs." Distinguishing individuals is nearly impossible. Now, a computer program analyzing photos and videos has accomplished that feat. The advance promises to reveal new information on bird behaviors...

The tool, called a convolutional neural network, sifts through thousands of pictures to figure out which visual features can be used to classify a given image; it then uses that information to classify new images. Convolutional neural networks have already been used to identify various plant and animal species in the wild, including 48 kinds of African animals. They have even achieved a more complicated task for elephants and some primates: distinguishing between individuals of the same species. Team member André Ferreira, a Ph.D. student at the University of Montpellier, fed the neural network several thousand photos of 30 sociable weavers that had already been tagged... [W]hen given photos it hadn't seen before, the neural network correctly identified individual birds 90% of the time, they report this week in Methods in Ecology and Evolution. Behavioral ecologist Claire Doutrelant of CNRS, the French national research agency, says that's about the same accuracy as humans trying to spot color rings with binoculars.

Ferreira then tried the approach on two other bird species studied by Damien Farine, a behavioral ecologist at the Max Planck Institute of Animal Behavior. The tool was just as accurate...

    Feed a trillion readily available pictures into such an algorithm (most uploaded voluntarily to the interwebz) and improve the accuracy a bit, there won't be a bird on the planet that can't be identified individually in any habitat.

    I, for one, welcome our bird watching overlords.

        I doubt it. Tagging gives information about bird migration and community mixing which wouldn't be available from pure counts of species by time and location.

            ...from photos.

            So unless you can figure out how to capture photos of a particular bird everywhere and everywhen, there is still a use for tagging that provides continual data.

      There is already such a neural net, Merlin Bird ID, based on about 2 million images from the Macaulay image library.

      You mean "Feed a trillion readily available and accurately labelled pictures into such an algorithm". Let me know when you find them - and how you knew you had found them.

    • Or human.

      Ba-ba-ba-ba-ba bird is the word...

      By the way, you clearly don't know much about birds. Because most of the time, they are sitting behind leaves and such. Only those that survived millions of years of.predators all around them, ... well ... survived, you know? :)
      Good luck, though, my shitty trained tensor twiddlers! ;)

      The article is about identifying individual birds, not bird species.
      Good luck getting a trillion readily available pictures for training that are tagged to identify individual birds.

    Most bird identification is done by listening to the bird sounds. It is great if you can also get a visual id but they can be damn hard to spot. My ornithologist friend is constantly listening to audio tracks of various birds to ensure they can identify the birds they encounter when doing field work.

    An interesting project I always wanted to do was to set up multiple audio recording devices positioned ~ 10 m apart from one another. Then when analyzing the audio, one can identify the birds and even triangulate their position. Being able to do this in real time would be amazing and would make an ornithologist's job much easier. They can do it for snipers firing at Humvees (a previous Slashdot posting) so it must also be possible for birds.

      Yup. I'm not even a hobbyist when it comes to bird watching, but pretty much every interesting bird I've spotted started with me thinking, "I've never heard that bird before."

      Identifying birds by their songs at least is already available.

      For now it's only an android app and not iPhone.

      Most of the time it works pretty well.
      I found that the noisiest birds in my back yard are the Cardinals and Robins, with a few other things such as woodpeckers.

      A lot has changed in six years.

      The "virtually impossible" task is now the easier of the two.

      You don't even need to train your own CNN. There is a Google Cloud API that can tell you if an image contains a bird in a dozen lines of Python.

        Plus, it's in "the cloud". And Google, to add insult to injury. So a complete no-go for any self-respecting developer.

          Any sane solution builds on existing technology.

          Do you mine your own iron ore with stone tools and fabricate your own transistors?

  • AI, we'll cram this technology down your throat, one way or another.
  • Was there overlap between what the humans couldn't identify and the AI? Or did the AI fail ridiculousy when it failed, like when it though a turtle was an AK-47? That's important to know.

  • 90%. 10% errors. How do they know that? They asked the human experts. What happens when they begin to rely on that system and the results are no longer doubted and there are few to no human experts left to correct the erroneous attributions? The errors become the truth. It is the same problem with all the expert systems they are trying to create to replace expensive humans.
