Data Mining, Machine Learning etc

For a couple of years I've been interested in data mining, machine learning, data analysis etc. Exactly why, I don't know, but probably it has something to do with one of my favorite book (series) since I was a teenager: Asimov's Foundation saga. In these books Asimov presents a new science called psychohistory, which can predict the future of the human race. When I later got hands of my two now favorite tools (Weka and R) I really got fascinated about this thing. Also, during the e-commerce hey days ('98 and forward some years), recommender systems, collaborative filtering, and of course stock predictions, started to be implementable.

Here is some of my texts about these things:
