AlphaGo Zero 演算法的 Open Source 實做

Leela 的作者 Gian-Carlo Pascutto 依照 paper 的描述寫完了,放在 GitHub 上的 gcp/leela-zero: I made an open source re-implementation of AlphaGo Zero: https://t.co/p8H6gGohA1 It just needs a good weights file. — Gian-Carlo Pascutto (@gcpascutto) October 24, 2017 不過他在 Twitter 上也提到了,open source 實做不是真正的困難,真正的困難在於訓練完的資料,那個部份需要大量的成本才有辦法作到: Every … Continue reading

AlphaGo Zero 的計算量

在 AlphaGo Zero 論文裡有提到,用同樣的硬體 (4 TPU) 可以用 89:11 碾壓 AlphaGo Master (今年年初與柯潔下的那個版本),主要是得力於更高品質的 neural network 以及更強的選擇能力 (後面這塊應該是將兩個 nerual network 簡化為一後的好處): This neural network improves the strength of the tree search, resulting in higher quality move selection and stronger self-play in the … Continue reading

Windows 將引入 TruePlay,推出作弊偵測的 API

在「Windows now includes gaming cheat detection at the system level」這邊看到微軟將會引入 TruePlay (然後跟 Sonos 的 trueplay 衝名 XDDD) 作弊偵測機制。 很明顯的會有隱私問題,而也很明顯的微軟說不會有隱私問題: As Microsoft notes, "to protect customer privacy, no data is shared or transmitted until permission is granted," and no information is … Continue reading

Facebook 也參戰參與 StarCraft 的 AI 測試,只是成績不太好...

Facebook 也參與了 StarCraft 的 AI 測試,不過成績不太好:「Facebook Quietly Enters StarCraft War for AI Bots, and Loses」。 不過跟 DeepMind 投入的項目不太一樣,Facebook 投入的是 StarCraft,DeepMind 投入的是 StarCraft II... 比賽有二十八組,Facebook 拿下第六名,但前三名都只是獨立愛好者: Final results released Sunday indicate Facebook still has a way to go: CherryPi finished sixth … Continue reading

用 Xbox 控制器操控潛艇

拿民用品當作軍事器材不是第一次了,不過拿來操作潛艇倒是蠻值得看一下的:「The U.S. Navy's most advanced submarines will soon be using Xbox controllers」。 在 lab 環境測試的畫面。 原因頗簡單,就是成本考量,而且很容易取得: The company says the photonic mast handgrip and imaging control panel that cost about $38,000 can be replaced with an Xbox controller that typically … Continue reading

歐盟對於盜版是否帶來傷害的研究

歐盟在 2014 年做了關於盜版與銷量的研究,結果一直被壓到最近才發表出來 (於是就大概可以猜到結論了...):「EU Piracy Report Suppression Raises Questions Over Transparency」。 “In general, the results do not show robust statistical evidence of displacement of sales by online copyright infringements,” the study notes. 甚至: The study found that piracy had a … Continue reading

AlphaGo 與柯潔下的三盤棋,包括了雙方的講解

在 Aja Huang (黃士傑) 的 Facebook 上看到 AlphaGo 與柯潔在烏鎮下的三盤棋的講解,這次的講解除了找柯潔與樊麾以外,更重要的是直接拿了與當時相同配備的 AlphaGo 出來使用 (只要柯潔想要看某些變化 AlphaGo 會怎麼應對,樊麾都會輸入進去跑模擬): 需要說明的是,視頻中參與覆盤的AlphaGo與烏鎮峰會比賽的版本和硬體配置(搭配4個TPU的單機版)完全一樣。希望大家享受這三盤精彩的對局,也能從這三個視頻的覆盤研究中有所收穫。祝大家觀影愉快。

PS4 下載速度很慢的原因

在「Why PS4 downloads are so slow」這篇作者花了不少力氣找出原因,發現 PS4 下載速度很慢是故意的... 另外討論了在什麼情況下會變慢,以及要怎麼避免的方式。 懶得看的人可以直接看 Conculsions 那段,主要的原因是 PS4 會因為背景程式而調整 TCP window size (就算背景程式在 idle 也會影響到下載的 TCP window size),進而影響速度: If any applications are running, the PS4 appears to change the settings for PSN store downloads, artificially … Continue reading

Hilbert curve

看到 Hilbert curve 的應用 XD:「Using Hilbert Curves to 100% Zelda」。 是碎形的應用... 作者想要將薩爾達的涵蓋率從 98.59% 拉到 100%: 而 Hilbert curve 剛好可以拿來解這個問題: 取自「File:Hilbert curve.gif」。 記錄起來 XD
