# Create regression dataset (from continuous-valued spectral library)¶

Create a regression dataset from spectral profiles that matches the given target variables and store the result as a pickle file.

Parameters

Continuous-valued spectral library [vector]
Continuous-valued spectral library with feature data X (i.e. spectral profiles) and target data y. It is assumed, but not enforced, that the spectral characteristics of all spectral profiles match. If not all spectral profiles share the same number of spectral bands, an error is raised.
Fields with target values [field]
Fields with continuous-valued values used as target data y. If not selected, the fields defined by the renderer is used. If those are also not specified, an error is raised.
Field with spectral profiles used as features [field]
Field with spectral profiles used as feature data X. If not selected, the default field named “profiles” is used. If that is also not available, an error is raised.

Outputs

Output dataset [fileDestination]
Pickle file destination.
