# Create unsupervised dataset (from spectral library)¶

Create an unsupervised dataset from spectral profiles and store the result as a pickle file.

Parameters

Spectral library [vector]
Spectral library with feature data X (i.e. spectral profiles). 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.
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.
