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.

My deep learning paper on predicting license plate auction prices made it to Financial Times! This is actually the first paper in a series: followup papers will use the prediction model to look into various investment anomalies. Somewhere down the road there will also be a field experiment where we will provide auction participants with an app to gives them estimates in real time.

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。
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.

Claudico battles Donger Kim, Jason Les, Bjorn Li, Doug Polk in Brains vs. AI at Rivers Casion, the first time that a computer program has played Heads-up No-limit Texas Hold’em in competition with top human players.

TensorFlow and CUDA 8.0

TensorFlow up and running with CUDA 8.0. Life-saving tip: always explicitly enter your CUDA and cuDNN versions during configuration.

My first impression is TF is a bit behind Nervana Neon in terms of training speed and ease of use. Too bad the latter now belongs to Intel, which clearly wants to promote its own Pentium-based Xeon Phi over Nvidia GPU.
