I don't use Seek, but the iNaturalist website filters computer vision matches using a "Seen Nearby" feature:
> The “Seen Nearby” label on the computer vision suggestions indicates that there is a Research Grade observation, or an observation that would be research grade if it wasn't captive, of that taxon that is:
> - within nine 1-degree grid cells in around the observation's coordinates and
> - observed around that time of year (in a three calendar month range, in any year).
For how the model was trained, it's fairly well documented on the blog, including different platforms used as well as changes in training techniques. Previously the model was updated twice per year, as it required several months to train. For the past year they've been operating on a transfer learning method, so the model is trained on the images then updated, roughly once each month, to reflect changes in taxa. The v2.0 model was trained on 60,000 taxa and 30 million photos. There are far more taxa on iNaturalist, however there is a threshold of ~100 observations before a new species is included in the model.
