Re: [Computer-go] Move Evaluation in Go Using Deep Convolutional Neural Networks

2015-01-10 Thread Stefan Kaitschick

 Let's be pragmatic - humans heavily use the information about the last
 move too.  If they take a while, they don't need to know the last move
 of the opponent when reviewing a position, but when reading a tactical
 sequence the previous move in the sequence is essential piece of
 information.

So maybe there is a greater justification for using last move info in the
playout than in the tree?

Re: [Computer-go] Evaluation function through Deep Convolutional Neural Networks

To me, that's the core lesson of MCTS - take your hands off that evaluation
button.

  The discussion on move evaluation via CNNs got me wondering: has anyone
  tried to make an evaluation function with CNNs ?

 My first thought was a human can find good moves with a glance at a
 board position, but even the best pros need to both count and use search
 to work out the score. So NNs good for move candidate generation, MCTS
 good for scoring?
