I am a complete novice at calling Weka from the command line, so I
am sure these will be somewhat trivial questions. I need to run a PCA for
dimensionality reduction. My questions are:
1. How do I call PCA from the command line?
2. Are there other attribute selection methods within Weka (supervised
and unsupervised) that have been found to perform better?
3. If "yes" to (2) then, could someone help with their command line
