AlphaGo 的開局庫分析

Facebook 上看到 Aja Huang 的訊息,介紹了 DeepMind 放出的新資料,由 AlphaGo 分析人類開局的各種勝率 (不是先前發表出來更凶的 AlphaZero,但不曉得是 AlphaGo Zero 還是 AlphaGo Master...)。

網站在 AlphaGo Teach: Discover new and creative ways of playing Go,盤面上的數字都是指黑棋勝率。

This tool provides analysis of 6,000 of the most popular opening sequences from the recent history of Go, using data from 231,000 human games and 75 games AlphaGo played against human players.

Explore the board and learn how AlphaGo's moves compare to those of professional and amateur players.

由於這是暴力法算出超大量的開局資料,而且是完整公佈在網路上,可以預料接下來的職業比賽,開局應該會參考這邊的資料進行修正...

星海爭霸 II 官方的 AI Workshop

Blizzard 公佈了在十一月的月初將會舉辦星海二的 AI Workshop:「Announcing the StarCraft II AI Workshop」。

On November 3 and 4, Blizzard and DeepMind will co-host the StarCraft II AI Workshop at the Hilton Anaheim hotel, next to the Anaheim Convention Center.

官方 (包括 DeepMind 團隊) 也會針對 SC2LE (Starcraft II Learning Environment) 與 SC2API (StarCraft II API) 提供交流:

Engineers and researchers from Blizzard and DeepMind will also be on-hand to meet with attendees and answers questions about the SC2LE and SC2API.

然後時間會跟 BlizzCon 2017 重疊 (目前看起來是卡到最後兩天),票是不能通用的:

While this event takes place during BlizzCon 2017, it is considered a separate event and is not part of the official BlizzCon program – therefore BlizzCon badges will not grant access to the AI workshop. However, we will be providing a limited pool of shareable BlizzCon badges that attendees of the AI workshop can use to check out BlizzCon and catch the StarCraft II Global Finals for inspiration on how to build superior AIs!

接下來應該會有不少消息出來... DeepMind 團隊的開發進度有可以跟頂尖選手競賽嗎?

AlphaGo 又要重出江湖了

DeepMind 家的 AlphaGo 又要重出江湖了:「Exploring the mysteries of Go with AlphaGo and China's top players」。這次將會跟中國的頂尖職業棋手對弈,裡面提到三種賽制:

The summit will feature a variety of game formats involving AlphaGo and top Chinese players, specifically designed to explore the mysteries of the game together. The games will include:

  • “Pair Go” — A game where one Chinese pro will play against another...except they will both have their own AlphaGo teammate, alternating moves, to take the concept of ‘learning together’ quite literally.
  • “Team Go” — A game between AlphaGo and a five-player team consisting of China’s top pro players, working together to test AlphaGo’s creativity and adaptability to their combined style.
  • “Ke Jie vs AlphaGo” — Of course, the centerpiece of the event will be a classic 1:1 match of three games between AlphaGo and the world’s number one player, Ke Jie, to push AlphaGo to (...perhaps beyond!) its limits.

有傳言是這樣打 (目前大家都抄來抄去...),但目前還沒看到正式的公告:

(一)5月23,25,27日 柯潔與AlphaGo三番棋:每方3小時,5次1分鐘讀秒;
(二)5月26日 時越、羋昱廷、唐韋星、陳耀燁和周睿羊5人團隊賽:每方2小時30分,保留3次1分鐘讀秒;
(三)5月26日 古力、連笑人機配對賽:每方1小時,1次1分鐘讀秒。

另外有一篇「Innovations of AlphaGo」講了不少年初 AlphaGo 連勝六十盤的對局給人類棋手的啟發。

另外 DeepMind 的 CEO,Demis Hassabis 前幾天剛好有給了一個演講,也是講了不少東西 (不過都是之前就提過的):

這樣來安排那幾天空時間下來...

DeepMind 跟 Blizzard 合作攻略 StarCraft II

DeepMind 宣佈與 Blizzard 合作,開發了 Star Craft II 的界面讓 AI 可以操作:「DeepMind and Blizzard to release StarCraft II as an AI research environment」:

Today at BlizzCon 2016 in Anaheim, California, we announced our collaboration with Blizzard Entertainment to open up StarCraft II to AI and Machine Learning researchers around the world.

這次比起圍棋更有意義的地方在於,圍棋是在完整資訊的情況下做出決策,但真實世界中經常是沒有完整的資訊就要做決策,這次的 StartCraft II 類似於這樣的環境,更接近於現實生活的情境:

StarCraft is an interesting testing environment for current AI research because it provides a useful bridge to the messiness of the real-world. The skills required for an agent to progress through the environment and play StarCraft well could ultimately transfer to real-world tasks.

另外考慮到電腦可以無限制精細操作每個單位,而人類有「操作速度」的問題,在規劃上會設限每分鐘可以操作的速度:

Computers are capable of extremely fast control, but that doesn’t necessarily demonstrate intelligence, so agents must interact with the game within limits of human dexterity in terms of “Actions Per Minute”.

來拉板凳繼續看下去...

谷李五番棋今天開打

GoogleDeepMind 所研發出來的 AlphaGo李世乭的「谷李五番棋」將在今天開打。

中國規則、兩個小時、一分鐘讀秒:

The matches will be played under Chinese rules with a komi of 7.5 (the compensation points the player who goes second receives at the end of the match). Each player will receive two hours per match with three lots of 60-second byoyomi (countdown periods after they have finished their allotted time).

將在韓國時間下午一點開賽,對我們也就是十二點開賽:

The matches will be held at the Four Seasons Hotel, Seoul, South Korea, starting at 1pm local time (4am GMT; day before 11pm ET, 8pm PT) on March 9th, 10th, 12th, 13th and 15th.

將會有大量的媒體講解直播,毫無疑問的,YouTubeDeepMind 這個頻道會有直播,目前看起來是早上的十一點半就會開始了。

其他的頻道,台灣已知的有:

不過我應該會到處看吧,中國的圍棋網站「围棋TV」也會在十一點半開始直播。

很多人都有猜測勝負,但自從去年十月贏了樊麾後,不知道成長了多少。其實都是在資訊不足的情況下猜測,在這種情況下,人類大獲全勝或是電腦大獲全勝都不意外...

也因此,五番棋的第一盤應該是最轟動的,因為可以看出 AlphaGo 長到什麼程度... 不過聽說第一盤 Google 只會拿單機版出來應戰?所以如果輸的很慘的話就會拿雲端版來戰?

啊啊啊我好想看啊...
