Sparse ARFF files

Hi,

I have data in sparse ARFF files. Here is an extract:

...
@ATTRIBUTE constraint2_B {v}
@ATTRIBUTE constraint2_A {v}
@ATTRIBUTE constraint2_C {v}
...
@DATA
{5 v,8 v,11 v,43 v}
{5 v,8 v,43 v}
{5 v,8 v,43 v}
...

According to the help information about the 'Read ARFF' operator, "the sparse ARFF format is currently only supported for numerical attributes." When used with the W-Apriori operator results are output, does this mean that this format is now also supported for nominal attributes?

Thanks,
Myse

    Hi,
    no, I don't think so. I'm not aware of any change in the last years to the read arf operator.
