Torch 2 is here

Post by pohl4711 »

I received a copy of Torch 2 just some hours ago from chesscom (thanks to A.Grant!) for testing.
Testrun started. If all works as expected, the result of Torch 2 should go online on my website on monday.

Stay tuned!

Do you know if Torch 2 has a dimension 3072 network? It is very good in other strong engines like Big-SF.

I like to look at things from a different perspective, in a very literal sense, so I don't see Torch as mirrored-halfka x 2560, but rather as N x 22528. So in some sense you could say that Torch has a dimension of 22528. Which makes us 733% more powerful at extremely balanced positions strictly in low sample size tests, compared to 3072 users.

By the time that Torch get 5 elo, Stockfish will get another 5 or more elo, the back wheel on the car will always follow the front, unless the front get rotated to the back :mrgreen:

Torch needs more than it.

Neural networks don't work that way. More neurons and dendrites aren't linearly mapped to greater ability.

CCRL's other lists are extremely compressed. 5 elo on those lists is right.

I'm exceptionally aware that Neural Networks don't work like this.
