Re: 2-part series that explains a0 better... 12/19/2017 ...

Note that the NN is just one part of the algorithm, and MCTS is the other. And the NN is conceptually a very easy-to-understand part, while the MCTS is comparatively complex. A NN is nothing but a collection of connected 'cells' (neurons). The connections are directional, i.e. connect an output of ...

Re: I can't believe that so many people don't get it!

All of the document can be true, except that a paragraph of how AZ learned SF8 first was left out. That would make them die-hard liars. Lying by omission is still lying. It would be considered gross scientific fraud. Yep. If I remember correctly you are doing this stuff even longer than me and I wo...

Re: 2-part series that explains a0 better... 12/19/2017 ...

This is article is a little misleading. There is no random playouts or even semi-random playouts as in the normal mcts tree. Once a leaf node is reached they call the NN and back up the score (no random playouts at all) okay... you may well be right... wish i knew more about NN's... they seem very ...

Re: AlphaZero Chess is not that strong ...

The results of the match AZ vs SF8 is translated in +100 Elo for AZ. The weakened part of Stockfish for this match is already known : 1) Only 1 GB hashtable (64GB to 128GB would have been more way more suitable) 2) 1 minute by move fixed time control 3) No opening book for Stockfish (AZ saved his o...

Re: AlphaZero - Tactactical Abilities

This is very precisely described in the AG0 paper. The NN has many layers. The first layer breaks up the board in overlapping 3x3 areas, and in each such area 256 patterns are recognized. But then many layers follow, (like 19 or 39), which can recognize 'patterns in the patterns', which in many cas...

Re: AlphaZero - Tactactical Abilities

NN = neural network. The NN produces an evaluation, in terms of winning probability (or actually score expectation), and move recommendations for searching. The NN was trained by showing it positions from the self-play games, and the result of that game, for predicting results from patterns in the ...
