Hi there brief explanation: UCI : contains the db files from UC/Irvine in arff form (which weka likes) cs639 : is various code I wrote in cs639 (XML & the web) course that I haven't the heart to throw away disc_proj : is stuff for a paper Prof Simovici & I wrote on discretization plus the some old code. When it appears somewhere, I will update this to have the current stuff. It also contains the stuff (code etc. from weka) sql_stuff : is what it says. Some little stuff I used to get going in learning SQL
