Similarity/Distance Methods using continuous variables

KNIME Analytics Platform
1

Hello,

 

I'd like to calculate a Tanimoto distance matrix using continuous variables (normalized to values between 0 and 1).

I tried using the Distance Matrix Calculate Node  which requires a vector as input though. Is there any node that can merge my rows and turn them into vectors containing Double values? (The only node I know is the Create Bit Vector Node but that one returns dichotomous values and not the original ones.) 

Or is there another useful approach?

 

Help is much appreciated!

Hi Michael, 

The KNIME implementation of the Tanimoto distance function works only for binary form (continuous one is not supported), therefore only a bit vector column is accepted as an input for this distance function. As you mentioned, a Create Bit Vector node can be used to create a bit vector column. 

 

Best,
