I generated a csv file with 167 attributes and around 5000 entries. One is a nominal attribute, two are dates and the rest is numerical.
I can import the file into the weka explorer without problems. But all clustering methods and most attribute selectors are greyed out. This still happens if I delete around 50 of my attributes. I only found ideas how to make it work with classifier methods but I need clustering or at least attribute selection. I used similar data before but with only 20 attributes and it worked, so I guess I need to further reduce the amount of attributes? But I'd really like to make some algorithm chose instead of me.
Can you advise me what I could change? Are there other tools that work with this many attributes? Or did I do a obvious mistake I am not finding?
