Subject Fail when converting Weka's ARFF (2.1) format to Mahout's Vector format.
Date Tue, 20 Jul 2010 14:35:55 GMT
I have run the converter to convert a Weka ARFF file to a Mahout Vector , the weka file contains
a missing(represent with '?' in weka) but the program failed and display the following error
   Exception in thread "main" java.lang.NumberFormatException : for input string : "?"

1) Why the converter don't accept missing value ('?')? 
2) How can I convert a data file (movie lens) to vector to execute the fuzzy kmean algorithm?

Thank you
