How to evaluate an AI model

How to evaluate an AI model:

1. Create a validation project with a set of areas that can be used for validation. For example areas that define where trees are located with the attribute FOLIAGE_TYPE.
2. Create an Inference Overlay and run your model contained in the ONNX file.
3. Create a Combo Overlay that detects these validation areas and subtracts the results from the Inference Overlay.
4. The difference between these validation areas and Inference Overlay determine how good the AI model works.
5. You can also use a TQL Queries to express this values in number, for example using SELECT_GRIDAREA_WHERE_GRID_IS_ID / SELECT_LANDPOLYGONS_WHERE_AREA_WITH_ATTRIBUTE_IS_FOLIAGE_TYPE.
