Create regression dataset (from text files)

Create a regression dataset from tabulated text files and store the result as a pickle file. The format matches that of the FORCE Higher Level Sampling Submodule. Example files (classification_dataset_force_features.csv and classification_dataset_force_labels.csv) can be found in the EnMAP-Box testdata folder).

Usage:

  1. Open the algorithm from the processing toolbox.

  2. Select the files containing your dependent and independent variables, then click run.

  3. The output classification dataset will be listed under Models in your Data Sources panel.

Parameters

File with features [file]

File with target values [file]

Text file with tabulated target data y (no headers). Each row represents the target values of a sample.

Outputs

Output dataset [fileDestination]

Pickle file destination.
