[computer-go] Neural networks

Hi! Is there some high-level reason hypothesised about why there are no successful programs using neural networks in Go? I'd also like to ask if someone has a research tip for some interesting Go sub-problem that could make for a nice beginner neural networks project. Thanks, --

Re: [computer-go] Neural networks

Neural network tend to work well in those cases where evaluation function is smooth, like backgammon. Even inbackgammon neural networks do give good results if situation has possibility of sudden equity changes like deep backgames and deep anchor games. Top backgammon programs 3-ply search on top

Re: [computer-go] Neural networks

In my opinion NeuroGo was quite succesful with neural networks. Magog's main strength came from neural networks. Steenvreter uses 'neural networks' to set priors in the Monte Carlo Tree. Erik On Wed, Oct 14, 2009 at 2:26 PM, Petr Baudis pa...@ucw.cz wrote:  Hi!  Is there some high-level

Re: [computer-go] Neural networks

Neural networks are not considered obsolete by the machine learning community; in fact there is much active research on neural networks and the term is understood to be quite general. SVMs are linear classifiers for hand-engineered features. When a single layer of template-matchers isn't enough,

Remi, what do you think of Numenta http://www.numenta.com/, a startup that is using feedforward/feedback networks to model learning and pattern recognition in the neocortex. Does this approach make sense or is it just startup hype?

Re: [computer-go] Neural networks - numenta

I'm not Remi, but I know a bit about Numenta. I gave a lightning talk at their workshop about a year and a half ago. A few people at Numenta are interested in using their software for Go, and I was working with one of them before my heart problems stopped that work. I do not think that

Re: [computer-go] Neural networks - numenta

Also not Remi, but... Numenta is a startup funded by Palm founder Jeff Hawkins. He started it following up on his book 'On Intelligence', which I think is a very interesting read. I'd suggest it as a reading to anyone considering applying some form of Neural simulation to Go or any other problem.

Re: [computer-go] Neural networks

[ Digression: Some ANN architectures are more biologically plausible than others. Neuromorphic Engineering is a good search term to see what's going on along those lines. (But for a beginner project, the standard multi-layer perceptron with backpropogation would still be the natural choice.)
