Hi,
I am brand new to Rapidminer, but what I have seen so far, I like very much. The first couple of tests run smoothly, but now - that I try to use a table with more attributes, I don't manage to configure it any more with Attribute Editor. Probably I am just using it wrongly, so your help would be greatly appreciated. I have the following difficulties:
- The first row contains the names. So I choose "use row as attribute names"
and it looks ok. However, when I save it, close it, and reopen the aml-file, I get errormessages like ... not being numeric. When I look at the table, it now contains the attribute names as names but also as row number one. I can delete the first row, but when I save and reopen the aml-file, it's there again.
- I would like to use a binominal label having the following values: TRUE, FALSE. So I choose "label" instead of "attribute" and "binominal". I save the descriptions. When I try to open them again, I get the following error message: Cannot map another string for binary attribute: already mapped two strings! I guess this is related to the first problem, since keeps importing the first row containing the labels, and tries to add them to the valus.
So, am I doing something wrong or is this a bug? The table I try to import is saved as .csv and looks the following:
konto_id;Gruppe;Kartenart;Sprache;alter_hki;geschlecht;zivilstand;anz_kinder;wohnen;anz_aktive_mte;ratio_mailings_reagiert_bisher;umsatz_6mm;anz_gueltige_karten;einkommensgruppe_id;kreditlimite;kundenkategorie_name;ist_ruecksender

Thank you very much for your help and kind regards
