Re: [computer-go] Pattern Matcher

Hi Vincent.

Please don't overquote, please read my posts carefully before asking
questions I have already answered and, before all else, don't waste my time
saying silly things or engage in religious fundamentalism.

For the rest I thank you for your interesting contributions here.

> Your problem is the statistical significance of a pattern.

Correct.

even have a

Incorrect on several counts.
First of all, your claim is a religious claim.
I on the contrary am the one doing the actual research, and I found that
when you take 125 billion patterns from half a million games, there are
about 1 million patterns that are very frequent (occur thousands of times).
Then there are about 3 to 4 million patterns that are less frequent (I end
up with a few dozen of them) and about 4 million patterns that occur once or
twice per 100,000 games. All the rest is rarer than that.

Now, the proof is in the pudding, the pudding being the ability to predict
moves in never-before-seen pro games.
When you say that it can't work but I see my system predicting long
sequences in pro games that are played after I trained my system, I see it
in fact does work.

> How many professional go-games do you have in your database?

I trained it with around 465,000 games, all high ama or pro.

I already mentioned in your quoted post that my database contains 52,000 pro
games.
But I discovered that ama games on certain Go servers can be of much higher
quality than (older) pro games.
I prefer to keep a secret which ama games that are, and why.
