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?
(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 There is also our paper linked, even so from 2009, not outdated.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,
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
