Detailed Description

Annotate a feature vector/slice with a label.

The Annotator adds an observation row for labeling the feature stream. The label can be set through the mrs_natural/label control. Note that this label control expects a natural number representation of the label. Also note that only one label can be given at each processing step and this given label is applied to all samples of the time slice.

Controls:

• mrs_real/label [w]: number representation of the label; classification (i.e. integers) are stored as a mrs_real and rounded later.
• mrs_bool/labelInFront [w]: toggle to put the label in front instead of at the end of the observations (which is the default).
• mrs_string/annotationName [w]: the name to use for the annotation.
