A new Computer Vision Model including 1,383 new taxa in 40 days

We released a new computer vision model today. It has 67,553 taxa, up from 66,214. This new model (v1.4) was trained on data exported last month on October 9th and added 1,383 new taxa to the model it has replaced (v1.3).

Taxa differences to previous model

The charts below summarize these 1,383 new taxa using the same groupings we described in past release posts.

By category, most of these 1,403 new taxa were insects and plants

Here are species level examples of new species added for each category:

We couldn't do it without you

Thank you to everyone in the iNaturalist community who makes this work possible! Sometimes the computer vision suggestions feel like magic, but it’s truly not possible without people. None of this would work without the millions of people who have shared their observations and the knowledgeable experts who have added identifications.

In addition to adding observations and identifications, here are other ways you can help:

  • Share your Machine Learning knowledge: iNaturalist’s computer vision features wouldn’t be possible without learning from many colleagues in the machine learning community. If you have machine learning expertise, these are two great ways to help:
  • Participate in the annual iNaturalist challenges: Our collaborators Grant Van Horn and Oisin Mac Aodha continue to run machine learning challenges with iNaturalist data as part of the annual Computer Vision and Pattern Recognition conference. By participating you can help us all learn new techniques for improving these models.
  • Start building your own model with the iNaturalist data now: If you can’t wait for the next CVPR conference, thanks to the Amazon Open Data Program you can start downloading iNaturalist data to train your own models now. Please share with us what you’ve learned by contributing to iNaturalist on Github.
  • Donate to iNaturalist: For the rest of us, you can help by donating! Your donations help offset the substantial staff and infrastructure costs associated with training, evaluating, and deploying model updates. Thank you for your support!

Below, I've shown published images along with the references (linked below) they are from

Arthrosphaera disticta

This drawing and the corresponding description from Pocock(11) of “Arthrosphaera disticta” does not match these. Not sure why:

Arthrosphaera dalyi

Arthrosphaera davisoni

Arthrosphaera zebraica

Arthrosphaera hendersoni

Arthrosphaera versicolor

References: 3
This looks very different from the yellow/black “Arthrosphaera versicolor” from Sri Lanka. And according to Wesener(10) Wesener, A. versicolor does not occur in India

Expert interview

I was very fortunate to have the opportunity to meet with Dr. Cheviri N. Ambarish, the author of references 1,2,3,4,6,8,9 above who is probably the world's foremost living expert on Arthrosphaera pill millipedes.

We browsed through and discussed various iNaturalist observations

Unfortunately, even through we found many distinctive groups (which I'll hopefully add into this post later) they don't have names and he was only fairly confidently able to ID and put names to observations of the following taxa.

Arthrosphaera fumosa

These have the distinctive smokey bluish color

Arthrosphaera disticta

These have distinctive colors and shapes

Arthrosphaera zebraica

These have distinctive colors,61270177&place_id=any

Arthrosphaera versicolor

While Wesener doesn't list these as occurring in India (only Sri Lanka), Ambarish worked with/photographed them in Reference 3 and was confident that these brownish spotted millipedes were indeed Arthrosphaera versicolor. It could be more study is needed to separate the Sri Lanka Arthrosphaera versicolor from the Indian Arthrosphaera versicolor as they look totally different.,79630224

While super interesting and I've very grateful for Ambarish, I have to say this study was a little frustrating. Clearly, more work is needed on this group to assign names to these taxa before we can identify many of them to species.

New Resolving Taxa with Unknown Relationships tutorial drafts

I posted a new 2 section tutorial on Resolving Taxa with Unknown Relationships to our nascent knowledge base here.

@kitty12, @thomaseverest, @xpda, @nschwab, @marceloamores, @invertebratist, @naturalist_aditya, @jeremygilmore, @lehelind, @rynxs, @tiwane, @stevejones, @alberto_colatore, @atotikov, @schoenitz, @beetledude, @t_e_d, @bdagley, @lwnrngr, @thebeachcomber, @reiner, @yorkniu, @rjq
thank you all for being such productive curators (each of you have resolved over 10 taxon flags this past month).

If you wanted to provide any feedback on these drafts I'd be very appreciative. I wrote it with working through this backlog of ~250 relationship unknown fish as the working example - which is a somewhat addictive queue to beat back following the steps in the tutorial if you have some time to kill.

Many thanks for all your help and excellent work as curators and I hope you're having a good start to the Northern Hemisphere winter wherever you are.
