What did you learn so far about neural nets? I recently looked into machine learning and naively thought I could find at least one practical fun tutorial "Here is a neural network API in C, you have to do that and this to let a simulated robot evade obstacles or learn to play Asteroids". Instead my (extremely superficial) search did find that neural nets are pretty arcane, genetic algorithms trapped in local minima and you are faster and better of coding logic yourself, developing a mathematical model to calculate results, instead searching for patterns in vast sets of data.
