Create classification dataset (from table with categories and feature fields)

Create a classification dataset from attribute table rows that match the given categories and store the result as a pickle file.

Usage:

1. Open the algorithm from the processing toolbox.

2. Select a table containing your classes as well as the fields containing features and labels, then click run.

   

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

Parameters

Table [vector]

Table with feature data X and target data y.

Fields with features [field]

Fields used as features. Values may be given as strings, but must be castable to float.

Field with class values [field]

Field used as class value.

Field with class names [field]

Field used as class name. If not specified, class values are used as class names.

Field with class colors [field]

Field used as class color. Values may be given as hex-colors, rgb-colors or int-colors.

Outputs
