-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
as somebody ask I will offer my actual CNN for testing. It has 54% prediction on KGS 6d+ data (which I thought would be state of the art when I started training, but it is not anymore:). it has: 1 2 3 > 4 libs playing color 1 2 3 > 4 libs opponent color Empty points last move second last move third last move forth last move input layers, and it is fully convolutional, so with just editing the golast19.prototxt file you can use it for 13x13 as well, as I did on last sunday. It was used in November tournament as well. You can find it http://physik.de/CNNlast.tar.gz If you try here some points I like to get discussion: - - it seems to me, that the playouts get much more important with such a strong move prediction. Often the move prediction seems better the playouts (I use 8000 at the moment against pachi 32000 with about 70% winrate on 19x19, but with an extremely focused progressive widening (a=400, a=20 was usual). - - live and death becomes worse. My interpretation is, that the strong CNN does not play moves, which obviously do not help to get a group life, but would help the playouts to recognize the group is dead. (http://physik.de/example.sgf top black group was with weaker move prediction read very dead, with good CNN it was 30% alive or so :( OK, hope you try it, as you know our engine oakfoam is open source :) We just merged all the CNN stuff into the main branch! https://bitbucket.org/francoisvn/oakfoam/wiki/Home http://oakfoam.com Do the very best with the CNN Detlef code: if (col==Go::BLACK) { for (int j=0;j<size;j++) for (int k=0;k<size;k++) { for (int l=0;l<caffe_test_net_input_dim;l++) data[l*size*size+size*j+k]=0; //fprintf(stderr,"%d %d %d\n",i,j,k); int pos=Go::Position::xy2pos(j,k,size); int libs=0; if (board->inGroup(pos)) libs=board->getGroup(pos)->numRealLibs()-1; if (libs>3) libs=3; if (board->getColor(pos)==Go::BLACK) { data[(0+libs)*size*size + size*j + k]=1.0; //data[size*size+size*j+k]=0.0; } else if (board->getColor(pos)==Go::WHITE) { //data[j*size+k]=0.0; data[(4+libs)*size*size + size*j + k]=1.0; } else if (board->getColor(Go::Position::xy2pos(j,k,size))==Go::EMPTY) { data[8*size*size + size*j + k]=1.0; } } } if (col==Go::WHITE) { for (int j=0;j<size;j++) for (int k=0;k<size;k++) {//fprintf(stderr,"%d %d %d\n",i,j,k); for (int l=0;l<caffe_test_net_input_dim;l++) data[l*size*size+size*j+k]=0; //fprintf(stderr,"%d %d %d\n",i,j,k); int pos=Go::Position::xy2pos(j,k,size); int libs=0; if (board->inGroup(pos)) libs=board->getGroup(pos)->numRealLibs()-1; if (libs>3) libs=3; if (board->getColor(pos)==Go::BLACK) { data[(4+libs)*size*size + size*j + k]=1.0; //data[size*size+size*j+k]=0.0; } else if (board->getColor(pos)==Go::WHITE) { //data[j*size+k]=0.0; data[(0+libs)*size*size + size*j + k]=1.0; } else if (board->getColor(pos)==Go::EMPTY) { data[8*size*size + size*j + k]=1.0; } } } if (caffe_test_net_input_dim > 9) { if (board->getLastMove().isNormal()) { int j=Go::Position::pos2x(board->getLastMove().getPosition(),size); int k=Go::Position::pos2y(board->getLastMove().getPosition(),size); data[9*size*size+size*j+k]=1.0; } if (board->getSecondLastMove().isNormal()) { int j=Go::Position::pos2x(board->getSecondLastMove().getPosition(),size); int k=Go::Position::pos2y(board->getSecondLastMove().getPosition(),size); data[10*size*size+size*j+k]=1.0; } if (board->getThirdLastMove().isNormal()) { int j=Go::Position::pos2x(board->getThirdLastMove().getPosition(),size); int k=Go::Position::pos2y(board->getThirdLastMove().getPosition(),size); data[11*size*size+size*j+k]=1.0; } if (board->getForthLastMove().isNormal()) { int j=Go::Position::pos2x(board->getForthLastMove().getPosition(),size); int k=Go::Position::pos2y(board->getForthLastMove().getPosition(),size); data[12*size*size+size*j+k]=1.0; } } -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAEBAgAGBQJWZvOlAAoJEInWdHg+Znf4t8cP/2a9fE7rVb3Hz9wvdMkvVkFS 4Y3AomVx8i56jexVyXuzKihfizVRM7x6lBiwjYBhj4Rm9UFWjj2ZvDzBGCm3Sy4I SpG8D01VnzVR6iC1YTu3ecv9Wo4pTjc7NL5pAxiZDB0V7OTRklfZAYsX4mWyHygn cr1pIb79/9QfBf/johmuutXJIwYfVG9ShR1+udbxs3aU3QDAbJJ4eTs8oj+NqFpg JolEEEg3wY693e77SqbUbjxR3kSsysoz9h1nKnR/ZjHByqlwNvSz9ho9eU0rKhaK GSQ22/c1VPIZhr24FYBbYNYweOzDtonLpuUFCPSnYVels3h/I/LlqV3MeDo6wuZ2 QCPp5+11o4JzvEt7A4zfJCtEOEH0W2/+IjRcIkAVOo65OV/pPsz2EjHehMU6PC6m vXA/kPx0jqUm1qSb0qCgMq5ZvSqfpcCY7JOlkEwkDBS1fty9sU0hqst3zXR0KGtn rFuoREmQYi/mkjZfS2Q4AHiZUDbDZUKzRegUA+gR/eKAmJsmWeTDEI9ZAXgxL0cB p1HGBNDEUKGk+ruq0gIe5vYygyBcJV0BbbBnweDjeZnlG8vLUAVoMF6V/q3gkZb1 P61rfE4d9dohfGBsZ+UWltRyWMj09ieR2G2zCDpIXyxEuoV6CTAlLzDuhmqFa2ma Fp3lK/uLhOucXwBtStdx =E47K -----END PGP SIGNATURE----- _______________________________________________ Computer-go mailing list Computer-go@computer-go.org http://computer-go.org/mailman/listinfo/computer-go
