This is from a few months ago but really interesting work from some university students that trained a popular machine learning model on data from iNaturalist.nz. The app is pretty good at identifying endemic species. The entire model is installed with the app which means that it works offline.
The Android version, which wasn’t ready when that story was written, is now on the Play Store. Haven’t had a chance to try it out yet.
Edit: Just tried it with a Tarata and it guessed it with 100% confidence. And it’s free. Cool.
