"Just upgraded to version 8. Error with Regularized Discriminant Analysis"

hughesfleming68

I am getting a Matrix is singular error with RDA in my process. Naive Bayes and other operators work fine. This is something new. This is a fresh install of 8.01 running on Windows 10 Pro. QDA fails but LDA works.

Best wishes to everyone at Rapidminer

Hmm that sounds odd. Moving this to bug reporting. Can you please reply with your XML process and your data set?

Hi Alex,

first of all, happy new year! Could you share your RapidMiner log file also? This might help us to find out what went wrong.

Sorry for the delay,

The error with RDA and QDA occurs with windowing and sliding window validation. LDA works fine. The error does not show up in normal cross validation. Disabling the second set of operators connected to the muliply operater allows the process to finish. The error did not show up in 7.11 where I originally created the process.

Kind regards,

Alex
