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.

That's cool! It sounds like you've given it a go, have you compared to international apps like PlantSnap to see if it gives better results given it's only looking for NZ species?

I hadn't heard about iNaturalist until I visited an exhibition at the Puke Ariki museum in New Plymouth that explains a project to classify species off the Taranaki coast and the publish everything on iNaturalist.

I haven't tested it against international apps. This app uses EfficientNetV2 https://arxiv.org/abs/2104.00298

There is a web version available too: https://what-is-this.cms.waikato.ac.nz/

It seems to fail on pictures of elephants so maybe it isn't trained on everything in the world...

Fails on the elephant test? That's kinda funny

I love that it's all working locally, does it handle plants as well? (All the images show animals)
