Eastern Hemlock (Tsuga canadensis) model on PC versus Supercomputer
I recently ran a model of Hemlock on my personal computer.
I modeled ~489 records; the Nautilus model used over 2,000.
From the model output:
This is a representation of the Maxent model for Tsuga_canadensis. Warmer colors show areas with better predicted conditions. White dots show the presence locations used for training, while violet dots show test locations.
This is not really a fair comparison, but the difference between the models with 489 records and 2000+ is interesting for comparing the predictions.
EECS model for Eastern hemlock is different. It uses more data, and it was run 20 times with 10% of the records reserved before being synthesized into one image.
I will post some additional comparisons for other trees in some later posts.
