association rule mining question

halaalrobassy

i have five dimension dataset and i used fp-growth process with association rules. i am confused from the rules appeared in promises and conclusion. for example :the first rule is : lib_cat = c_mid with 0.7 of support and 0.79 if confiedence , the second rule is opposite : c_mid = lib_cat with 0.7 support and .97 of confiedence .and this happen to must of the rules generated . 
my question, is this true or no??? 
i attatched the rules to be clearer. hope you can help me in explaning what is the reason of this and if it is true or wrong

the process as the following:

Hello

Please pay attention to the link also I think your process is not correct. please try to make your process like the one that you see in the link then show the result in order to compare both processes.

Also this is an example from studio

halaalrobassy

what do you mean by set role process, actually ,my data is preprocessed so, the there many processes before using fp-growth algorithm, but if set role process will make difference , i will use it .so please tell me why you have use it before fp-growth algorithm

Hello @halaalrobassy,
Set role Operator is used to change the role of one or more Attributes.( for more information you can use this link)
https://docs.rapidminer.com/latest/studio/operators/blending/attributes/names_and_roles/set_role.html


Also the screen shot is for a sample that we have in studio. 
According to the definition of set role and the example that you see is used to define the role of an attribute which you can see in screen shot


Also this is Tutorial for set role operator in studio  

I hope this helps
