Variance Uncertainty Scorer

This Node Is Deprecated — This version of the node has been replaced with a new and improved version. The old version is kept for backwards-compatibility, but for all new workflows we suggest to use the version linked below.

Calculates the variance of a class probability distribution.

Options

Column Selection: Include the columns containing the class probabilities. The values must sum up to 1 for each data row.
Output column name: Set the name of the appended output column.
In case of invalid input...: Specify the action if a data row of the input is invalid. Invalid could mean a missing value in the input or an invalid distribution (the probabilities must sum up to 1). If fail is selected, the node will fail. Otherwise, the node just gives a warning and puts missing values in the output for the corresponding rows.

Input Ports

: Table containing two or more columns containing class probabilities that sum up to 1.

Output Ports

: Input data with an appended column that contains the uncertainty score.
