How does the knime correlation filter works?

Hi , i have just started using knime recently and tried using correlation filter to streamline my data.

I am curious on how does the node actually interpret the threshold value inputted to it to filter out the data ?

Thanks

Hi @Tseraga,

The Correlation Filter node looks for the column with the most correlated columns in an iterative procedure. The threshold you set in the configuration dialog actually determines the definition of “correlated column”. That is, two columns are said to be correlated if their correlation coefficient is greater than the threshold.

If you are interested in an example, take a look at https://workflows.knime.com/knime/hub/workflows/50_Applications%3A21_Model_Selection_and_Management%3A01_Model_Selection_Sampled.

Best,
Stefan
