Good day! I'm trying to read an excel file (using the Read Excel operator) in RapidMiner, but when I look at the results, the confidence and prediction are all the same values. However, when I use a CSV file (using the Read CSV operator) as the unlabeled data, it seems to predict it properly. The CSV file and the EXCEL file are both the same data, just in different formats, so I don't understand why the Excel version would give strange results. Could I have missed a setting or something? Any help will be appreciated.
Thank you very much!
