These were the real-world data sets used on my MLP lecture. I duplicate them here for convenience, greatfully acknowledging the original sources: Iris flower measurement data is from: UCI Machine Learning Database www.ics.uci.edu/~mlearn/MLRepository.html jEdit software metric data is from: PROMISE data sets http://promisedata.org/ As the original files had text for class labels, I have prepared versions with numerical class, and no annotations (more suitable for the dlmread() function of Matlab) Correspondence: Paavo Nieminen
