dcase_util.processors.OneHotEncodingProcessor

class dcase_util.processors.OneHotEncodingProcessor(label_list=None, focus_field='scene_label', time_resolution=1.0, length_frames=1, length_seconds=None, allow_unknown_labels=False, **kwargs)

One hot encoding processor

Constructor

Parameters

label_listlist

List of labels in correct order

focus_fieldstr

Field from the meta data item to be used in encoding

time_resolutionfloat > 0.0

Time resolution used when converting event into event roll.

length_framesint

Length of encoded segment in frames

length_secondsfloat > 0.0

Length of encoded segment in seconds

allow_unknown_labelsbool

Allow unknown labels in the decoding. If False, labels not in the given label_list will produce an error. Default value False
