A new Computer Vision Model (v2.2) including 1,603 new taxa

We released a new computer vision model today. It has 72,511 taxa up from 71,286. This new model (v2.2) was trained on data exported last month on February 19th and added 1,603 new taxa.

Taxa differences to previous model

The charts below summarize these 1,465 new taxa using the same groupings we described in past release posts.

By category, most of these 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!

I have a silly question... how do I download the .tflite model released today?

I wonder... which region usually receives the most new species added to the computer model each month? Seems to be either North America, South America, Africa, or Oceania?

I find the ID suggestions from the computer vision model really useful, please keep improving the model - its a great tool.

@dan686 The inclusion of taxa in this model is data-driven so if it's not included it is because they're missing data (verifiable observations with images). So if you want to see them included, you know what to do ;)

Link fixed, thanks @apseregin and @optilete.

@dan686 about 100 photos, say 60 obs - and it will be included with the next CV update.

AI and ML will replace most iNat identifiers but will never replace Observations! So keep on!

Fantastic! Especially impressed to see the spider Corythalia conferta enter the model with 1300+ observations already. The taxon was only added in December 2022 and @michelotto and others have been doing a huge clean-up of observations previously identified only to genus

Quite a lot of new Mollusca, thanks!

1603 taxa in 40 days that means each day 40 new taxa are added to the model. The system is really flowing. Love to see all the updates coming. I'm always glad when an update arrives and checking out to see what is added. Looking forward for the next update around 10th May and in the meanwhile trying to help mostly with observations and some identifications.

@nschwab I've been iding them for ages already 😂 nearly at 3000!

Woo hoo! Glad to see the taxon split of Brodiaea rosea has made it into CV. Some quick testing suggests that CV still favors B. coronaria as an ID for B. rosea observations, but it does offer B. rosea second. I'll be interested to see if it learns the distinction as the dataset gets more accurate.
