MKL Limited to 1 Thread in Anaconda

If you have used the preload trick to use Math Kernel Library (MKL)  with an early version of Anaconda, you will find that under Anaconda 4.4 MKL is limited a single thread no matter what settings you enter. The solution is to remove the LD_PRELOAD entry for MKL, log out, log back in and you should be good to go.

今日去旺電入貨, 店員話掘coin堀到啲高階顯示卡全部貴曬,有錢都未必有貨。(這並非投資建議。)

《金融時報》提及我以深度學習—依家興叫「人工智能」—估計車牌拍賣價錢的研究。

除了AlphaGo,其實還有很多值得留意的人工智能發展。例如現在正在美國進行中的無上限德州撲克大賽,由Carnegie Mellon大學的人工智能對世界上最頂尖的人類選手進行20天的比賽。到目前為止戰況可說是一面倒向電腦一方。
和圍棋不同,德州撲克是一種有隱蔽資訊的遊戲,參賽者並不知道對手以及未派發的牌為何。因此德州撲克相比起圍棋對解決很多現實中的問題意義更大。
Texas Hold’em is a much more interesting game than Go when it comes to real-world artificial intelligence application, since many important real world issues inherently involves imperfect information. 5 days into the game and the human pros are losing badly.
