KNIME Base Nodes version 4.2.0.v202007101308 by KNIME AG, Zurich, Switzerland
Filters out double-compatible columns, whose variance is below a user defined threshold. Columns with low variance are likely to distract certain learning algorithms (in particular those which are distance based) and are therefore better removed.
Note, the input table should not be normalized with a Gaussian normalization or any other normalization technique which changes the variances of the input.
