Re: [Computer-go] Deep Zen - do we have a race now?

Hi Petr, to clarify a bit: pylearn2 specifically comes with a script to convert a model trained on a GPU into a version that runs on the CPU. This doesn't work very well though and the documentation points that out too. According to the dev commens that is down to how Theano, the framework pylear

Rémi, Nvidia launched the K20 GPU in late 2012. Since then, GPUs and their convolution algorithms have improved considerably, while CPU performance has been relatively stagnant. I would expect about a 10x improvement with 2016 hardware. When it comes to training, it's the difference between runni

Also, reading more of that pull request, the guy benchmarking it had old nvidia driver version which came with about 50% performance hit. So I'm not sure what were the final numbers. (And whether current caffe version can actually match these numbers, since this pull request wasn't merged.) On W

I tried Detlef's 54% NN on my machine. CPU = i7-5930K, GPU = GTX 980 (not using cuDNN). On the CPU, I get 176 ms time, and 10 ms on the GPU (IIRC, someone reported 6 ms with cuDNN). But it is using only one core on the CPU, whereas it is using the full GPU. If this is correct, then I believe

[Computer-go] Deep Learning learning resources?

2016-03-02 Thread Darren Cook
I'm sure quite a few people here have suddenly taken a look at neural nets the past few months. With hindsight where have you learnt most? Which is the most useful book you've read? Is there a Udacity (or similar) course that you recommend? Or perhaps a blog or youtube series that was so good you w

This online book by Michael Nielsen is a fantastic resource: http://neuralnetworksanddeeplearning.com/ It builds everything from the ground up in easily digested chunks. All the required math is in there, but can be skipped if just a general understanding and basis for application is desired. High
