Tasks¶

There are three tasks within the MillionTrees package.

Official¶

The first task is to create the best global detector for individual trees given a set of training and test data. Datasets are split randomly, reflecting information within localities. This is consistant with how most applied users engage with models, by fine-tuning backbone models with sample data from a desired locality.

Zero-shot¶

The second task is to create a zero-shot detection system to generalize across geography and aquisition conditions. Selected datasets are held out from training completely and used for evaluation in new conditions. This is a challenging task with no local training data.

Cross-geometry¶

Off the shelf tools often limit users for a single annotation type. We have ‘point’ models, ‘box’ models and ‘polygon’ models. To create truly global models for biological inference, we need models that can use all available data, not just one annotation geometry. In particular, polygon annotations are very time consuming to create, but are often desirable for downstream usecases. We opted against polygon training sources, for example polygons to points, as this is an unrealistic, or atleast, very uncommon downstream use case.

Boxes to Polygons¶

All box sources are used to train and predict all polygon sources. There is no local data from the test localities in train.

Points to Polygons¶

All point sources are used to train and predict all polygon sources

Points to Boxes¶

All point sources are used to train and predict all box sources.
