Regression workflow

The regression workflow combines regressor fitting, map prediction and accuracy assessment.

Parameters

Training dataset [file]

Training dataset pickle file used for fitting the regressor.

Regressor [string]

Scikit-Learn Python code specifying a regressor.

Raster layer with features [raster]

A raster layer with bands used as features.

Number of cross-validation folds [number]

The number of folds used for assessing cross-validation performance.

Default: 10

Open output report in webbrowser after running algorithm [boolean]

Whether to open the output report in the web browser.

Default: True

Outputs

Output regressor [fileDestination]

Destination pickle file.

Output regression layer [rasterDestination]

Raster file destination.

Output regressor performance report [fileDestination]

Output report file destination.
