Module Contents

class dasf.feature_extraction.transform.ConcatenateToArray(flatten=False)

Bases: dasf.transforms.base.Transform

Concatenate data from different Arrays into a single array.

Parameters

flattenbool

If the arrays must be flatten prior concatenating. If False, the arrays must share the shape of last dimansions in order to be concatenated (the default is False).
