Random Number Generation

Is there a way of  generating a random table of data?

What I'm trying to achieve is to generate a random set of parameters for use with the RProp MLP predictor.

I have used actual data to train the model and test; but I would like to use 'hypothetical' to test the model further. (20 Parameters; so there is a lot of gaps to fill).

In Excel I would use "=(RANDBETWEEN(1,100))/100)". I could do this anyway and import the data, but thought it would be nice if it could be created within KNIME?




Hi Martyn,

(my favourite topic :-))

Data generation with KNIME is much better as with Excel. See here a list of all of our data generation node: https://www.knime.org/datagen . There is also our paper linked, even so from 2009, not outdated.

The one you are looking for is the Random number assigner.

Cheers and happy generating,


Perfect, Thank you Iris

There is also a Random Number Generator node in the Vernalis community plugin - does pretty much exactly what it says - doubles or integers, how many do you want, min/max values, and do you want to allow duplicates
