Racing ANN

aparaske · 2006-10-06T18:39:10

Hi, I created a neural network for a racing game. The track consists of 157 checkpoints. A racing line is defined between each checkpoint. Inputs: - Direction error of current racing line - Direction error of next racing line - Position error in respect to racing line - Speed Outputs: - Gas - Brake - Steering The ANN is trained by collected training data sets while the user is driving the car until enough training data sets are collected. There s an XML file that contains the settings (how many data sets to collect, how many training runs, the number of layers and nodes etc) and is loaded on startup. I currently drive the car with first gear on only, to see if it works properly. Unfortunately, the ANN does not control the car properly, and i cant imagine why. Even though i dont use brakes at all during training, the car will halt before the first turning. Does anyone have any idea why this happens? Would a training data analyser(filters data before feeding it to the network so that there arent a lot of user mistakes that the ANN learns) help?

I want to design AI with neural networks, to get a glipse of how they work and what are capable of.

FYI, you should always begin by a literacy review... there are some excellent papers & studies that compares ANN to other regression methods. Maybe I should write one for GameDev.

How can I reward the network? Could you direct me to a source where i can find information and examples of what you're talking about?

Like I said, an evolutionary neural network is the easiest way. I think the AI-Junkie website has a tutorial on EANNs, otherwise it's pretty easy to Google for both that and reinforcement learning.

Why would one need a review of how literate people are??

(Sorry, couldn't resist ;D)

I already did a literacy review (it was a final year project). However, it was quite small (3 pages) since there was a limit.
