Converting data to LibSvm format

Hi all,

Is there a way to convert any kind of dataset to LibSvm format for learning to rank tasks?

Since I am working with ranklib algorithms I need data in that specific format.
I wish to creare a pre-processing workflow in which I can convert any given dataset to the right format. Is it achievable with standard knime nodes? Or shall I write a script and then use the Python script node?

Best Regards,

Hi @Fonzo454 ,

Knime have a extension for it…
