This node converts a table to a number vector used by the Deeplearning4J Integration. This node is only used for testing purposes in order to validate the conversion. The node tries to convert every input column contained in the table. Possible target columns can be specified in the node dialog which will be converted into a separate vector.
The KNIME Deeplearning4J Integration has been marked as legacy with KNIME Analytics Platform 5.0 and will be deprecated in a future version. If you are using this extension in a production workflow, consider switching to one of the other deep learning integrations available in KNIME Analytics Platform.
