GSP Operator: Wrong connection while passing sequential patterns to Create Association Rules out of

Hello,

while the GSP operator works fine I cannot pass the pattern to the Create Association Rules operator. I get the following error message:

The GSP input port tells that one attribute is missing, which is not the case. It's one of RapidMiner's warnings which can be ignored.

 

Can someone help? The GSP tutorial in the Operator Reference Manual doesn't use the Create Association Rules operator, which is nessecary, isn't it?

 

Kind regards,

Ina

Re: GSP Operator: Wrong connection while passing sequential patterns to Create Association Rules out

Hi,

 

Generate Ass. Rules is usually used with FP-Growth. I think it does not make sense to use it with GSP.

Re: GSP Operator: Wrong connection while passing sequential patterns to Create Association Rules out

The problem is that you're trying to pass the PAT port (GSP) to the ITE port (Create Association Rules).  

 

You will need to put a FP-Growth on the EXA output port from the GSP and then connect the Create Associaiton Rules.


Like so.
