Re: Cross Distances operator : Weird results

Hi all,

 

I performed the calculation of "distances" manually using RapidMiner (not with ......Excel this time @sgenzer...)

Stop me if i'm wrong, but I considered that : 

 - for nominal attributes : Distance_Attribute_x = IF(Attribute_x[Employee caracteristics] == Attribute_x[Position],0,1).

 - for numerical attribute : Distance_Attribute_x = (Attribute_x[Employee caracteristics] - Attribute_x[Position])^2.

then Distance = SQRT(sum(Distance_Attribute_x)).

 

I obtained the following results : 

 

HR_Sourcing_7.png

for recall, I obtained the following results with the Cross Distances operator: 

 

HR_Sourcing_8.png

We see that there is only one "good result".

 

Here the entire process :

and here the Excel file :

I hope that I help to advance the reflection on the Cross Distances operator.

    hi @lionelderkrikor so I played with your csv files and I believe it is a metadata problem (bug).  Here's how I come to this conclusion: if you do this process, you get the expected result:

    However if you remove unused values (which only affects the metadata), you get the same problem as before:
