SAGE

Data explorer

Inspect the species of the dataset: You will see its native range, sampled cells, occurrence records, and model predictions by the Optimized DeepSDM. If you want to see how the choice of threshold influences the model performance or see at which locations the model ist most certain, switch to the thresholded predictions view. Move the slider to change the threshold and see how the predictions change. To keep the explorer lightweight, predictions for all species are shown at 0.25° (about 28 km). Higher-resolution maps can be generated with the codebase.

Benchmark setup

Data preparation

Occurrence records are aggregated to a 1 km equal-area grid to reduce spatial clustering. Records falling onto cities are removed. Training records come from GBIF and evaluation plots from sPlotOpen.

Range masking

Training and evaluation data is restricted to the species' native ranges from POWO. Out-of-range locations are ignored rather than counted as absences.

Predictors

Fifty-two environmental predictors are provided on the same 1 km grid.

Predictions shown on the map

The surface and the scored plots above come from the Optimized DeepSDM — the DeepSDM baseline with the aggregation, subsampling, architecture and loss changes applied, the strongest deep model in the leaderboard. Its weights are in the released-models record on Zenodo, linked below.
