Add Noise


Synopsis

Adds noise to existing attributes or add random attributes.


Description

This operator adds random attributes and white noise to the data. New random attributes are simply filled with random data which is not correlated to the label at all. Additionally, this operator might add noise to the label attribute or to the regular attributes. In case of a numerical label the given label_noise is the percentage of the label range which defines the standard deviation of normal distributed noise which is added to the label attribute. For nominal labels the parameter label_noise defines the probability to randomly change the nominal label value. In case of adding noise to regular attributes the parameter default_attribute_noise simply defines the standard deviation of normal distributed noise without using the attribute value range. Using the parameter list it is possible to set different noise levels for different attributes. However, it is not possible to add noise to nominal attributes.
