Or, worse, there were repeats in the 28 wins. Even in the 10 games they showed some looked quite similar.

A NN is filled with data driven by an algorithm with a goal, then when filled it is used by another algorithm to do the specific things the programmer had in mind.

We learn driven by intelligence, a NN is just stupid data -- without any intelligence -- the intelligence is of the programmer who created the data. No NN learns by intelligence.

Taking opinion polls on facts among people without the information to verify them or not is not getting us closer to truth. Maybe a poll about was the match fair?
What facts?

It's a biased paper.

What people choose to believe aren't necessarily facts.

BTW, you are late moving in, maybe you can comment on some of my posts. And for the record - I am in follow_the_money_mode :wink:

Perhaps 'intelligence' is just stupid data? But a lot of it?

We had one of those. The membership was nearly equally divided, just as they are so far in this poll.
Deasil is the right way to go.

Good point Carl, and one I didn't think about.
