Skip to 0 minutes and 4 seconds Hello! My name’s Ian Witten, I’m from the University of Waikato here in New Zealand, and I want to tell you about our new, free, online course – Data Mining with Weka. We’re overwhelmed by data in the world today. Every time we check out an item at the supermarket, every time we swipe our credit card, every time we send an email, every time we type a keystroke on our computer, every time we make a phone call, send a text, walk past a security camera – we all generate a little bit of data.
Skip to 0 minutes and 35 seconds Data mining is about taking this raw data, and transforming it into something more useful: information, perhaps; or predictions, predictions about what might happen next, predictions that can be used in the real world. The real aim of this course is to take the mystery out of data mining, to give you some practical experience actually using the Weka toolkit to do some mining on the data sets that we provide, to set you up so that, later on, you can use Weka to work on your own data sets and do your own data mining. It doesn’t involve any programming or anything like that. You’re going to be using the tools that we provide, the Weka tools.
Skip to 1 minute and 13 seconds It might help to know a little bit of elementary statistics, like means, variances, standard deviations, and so on. You might see a couple of mathematical formulae, but I’ll explain those, so don’t worry about that. You don’t really need any specific mathematical background. So that’s it – Data Mining with Weka, coming soon to a computer near you. I’m looking forward to it, and I hope to see you there. Bye for now!
