Automated process for k-means clustering (for each weekday)


I have a clustering with feature “weekday”. I have created a separate clustering for each day and saved the results in 7 Excel tabs.

Question: How can I automate this process?

Thansk in advance,


Hi @Michel777

For this you can use the GroupLoop node (where the groups are created by weekday).
The GroupLoop node creates a flow variable (Day of week name), that is used in the Excel writer to label the tabs. See KNIME_project4.knwf (36.3 KB)
