I didn't implement the machine learning algorithms for myself, because there are some really good packages out there and I know I don't have the smarts to better them. Keep in mind that I didn't really have any success: There seem to be two main ML packages, Weka and Orange. I personally preferred Orange, it has a nice graph-based UI for linking various components together; when you've figured that out it can script…

Thankyou for the detailed reply. Yeah I hated using weka at uni. I'll look into Orange. "I don't know if the track conditions are important, how much breeding or the age of the animal really matters etc." Yeah, feature selection is a tough one. I'd thought that the system would pick up on good indicators by itself, but it might well be that that has to be a manual decision. "Just make sure you've tested your predicti…

Genetic algorithms can be used to determine the (close to) best combination of features from all the features you have access to.

My ongoing quest to make money predicting horse races. So far I've not made a dime, and don't really expect to, but the faint hope of future monetary rewards keeps me going. The real payoff has been that in the process I've learned all sorts of things: about Python, data mining, working with large datasets, machine learning...

I met a guy (I can give more details offline) who worked for an international gambling syndicate based in HK. Software written by teams in Shenzhen running on servers in HK fed by data from handicappers in Australia directed bettors to place bets at tracks all over the world. They were making something like 15-20% returns. As you can imagine, he had some crazy stories. At the time I was thinking about something similar (not horses) but eventually moved on to more respectable things (grad school.)

a small note site. Pages are written in markdown, and then displayed in HTML. It exports to plain text, and syncs with Simplenote. The goal is a super low barrier to entry. I want it to be a middle ground between my thoughts and my hard drive.

I'm also working on my first iPad app.
