发帖数: 4196 | 2 Computers have already bested humans at chess, checkers, and on the TV game
show Jeopardy!, and now one will attempt to assert its dominance in the
ancient board game of Go.
In January, an AI program developed by Google's DeepMind group called
AlphaGo beat the European human champion. This week, it will go head-to-head
with Korean player Lee Se-dol, the world's top Go player over the past
decade, in a five-match tournament in Seoul, South Korea, which will be
streamed live via YouTube.
The match... 阅读全帖 |

发帖数: 534 | 3 In his prime, lee sedol had won consecutively 18 (or is it 21?) pro games.
Alpha go barely did 7 (some do not consider the european champ have pro
level).
Take it easy.
Why can't it be possible that human figure out the style of computer, and
find a way.
Also, current pros dare not claim that they could beat Go seigen. Why should
we assume that the machine can.
沉着点，潇洒点，别那么没出息。 |

发帖数: 8443 | 4 Lee Sedol has bested AlphaGo, brilliantly, in Game 4 of the 5 game challenge.
The big question now is who will win Game 5?
Personally, I'm rooting for Lee Sedol. Why? I hope he will adapt his
gameplay, based solely on the games so far, win again, and showcase the
learning power of the human brain!
Biological brains are amazing. We have watched Lee Sedol deliberately change
his style of play over this week, fluidly and consciously adapting and
exploring. Presumably he will use the experience of w... 阅读全帖 |

发帖数: 6612 | 13 根据Bradley-Terry Model， alapho go和lee sedol比赛赢棋的概率是根据排名gamma
rating决定的。
P(赢棋） = （alpha go的排名积分）/（alpha go的排名积分 + lee sedol的排名积分）
如果 P = 1, alpha go的排名积分是无穷大。 |

质纪事本上。并不存在于市场，也没有CUSIP/ISIN/SEDOL。因为这部分美债在市场上根
本不存在，根本无法出售。
另一类美债是间接购买，中资公司委托agent从二级市场购买。这部分虽然理论上可以
抛售，但都是以亿为单位的大单，拆零出售技术难度很大。即使有agent愿意给你这么
干，这种恶意抛售马上就会暴光，并且很难迅速完成。除非能找到不介意美国政府警告
而且有巨大财力立刻接盘的势力。世界上还没有这样的势力。而且这样的交易一般只能
按outlaw规矩，即售价为债券面值的30%~50%，大规模的话更低。 |

The ultimate test of AlphaGo’s capabilities, though, will come in March.
DeepMind has persuaded Lee Sedol, a Korean player widely regarded—like Mr
Kasparov in his day—as one of the best-ever players, to take on their
machine in a series of games in Seoul. If AlphaGo wins—and given its
performance against Mr Hui, that seems like a distinct possibility—then
human brains, and their possessors, will have to cede another defeat to the
machines. |

more possible Go moves than there are atoms in the universe so it's been
incredibly tough for machines to crack Go.

classic strategy game Go is reported in this week’s Nature. Go has been
regarded as an outstanding ‘grand challenge’ for artificial intelligence
owing to its large search space and the difficulty of evaluating board
positions and moves. The findings provide hope that human-level performance
could potentially be achieved in other seemingly intractable artificial
intelligence domains.
