Create regression dataset (SynthMix from classification dataset)

Create synthetically mixed regression datasets, one for each category. Results are stored as <category.name>.pkl files inside the destination folder.

Parameters

Classification dataset [file]

A classification dataset with spectral endmembers used for synthetical mixing.

Number of mixtures per class [number]

Number of mixtures per class

Default: 1000

Proportion of background mixtures (%) [number]

Proportion of background mixtures.

Default: 0

Include original endmembers [boolean]

Whether to include the original library spectra into the dataset.

Default: True

Mixing complexity probabilities [string]

A list of probabilities for using 2, 3, 4, … endmember mixing models. Trailing 0 probabilities can be skipped. The default values of 0.5, 0.5,results in 50% 2-endmember and 50% 3-endmember models.

Default: 0.5, 0.5

Allow within-class mixtures [boolean]

Whether to allow mixtures with profiles belonging to the same class.

Default: True

Class probabilities [string]

A list of probabilities for drawing profiles from each class. If not specified, class probabilities are proportional to the class size.

Outputs

Output folder [folderDestination]

Folder destination.
