ExplicitSelector(**kwargs)

class src.utils.ftransf.explicit_selector.ExplicitSelector(**kwargs)

Author:

Alberto M. Esmoris Pena

Class for transforming features by discarding or preserving exactly those given as input.

Variables:

• fnames (list of str) – The names of the features that must be either discarded or preserved.

• preserve (bool) – The flag governing whether to preserve the given features (True, default) or not (False).

static extract_ftransf_args(spec)

Extract the arguments to initialize/instantiate an ExplicitSelector.

Parameters:

spec – The key-word specification containing the arguments.

Returns:

The arguments to initialize/instantiate an ExplicitSelector.

__init__(**kwargs)

Initialize/instantiate a ExplicitSelector.

Parameters:

kwargs – The attributes for the ExplicitSelector.

transform(F, y=None, fnames=None, out_prefix=None, F_fnames=None)

The fundamental feature transform logic defining the explicit selector.

See FeatureTransformer and feature_transformer.FeatureTransformer.transform().

Note that, to the contrary of many other feature transformers, the logic in this transform method is not adequate to be called from the corresponding transform_pcloud (as it has been overriden to efficiently deal with point clouds as input).

Parameters:

F_fnames (list of str) – The names of the features (columns) for the input feature space matrix F.

transform_pcloud(pcloud, out_prefix=None, fnames=None)

Apply the explicit selector to a point cloud, overwriting the parent’s logic to send the names of the features (columns) of the matrix F.

See feature_transformer.FeatureTransformer.transform_pcloud().
