Re: I can't believe that so many people don't get it!

Google exactly knows the hardware advantage they had during the match and it isn't mentioned in the paper. It is mentioned exactly in the paper which hardware they used (4 TPUs). The TPUs and their performance has been described in other papers, to which they refer. I assume they picked such a low ...

Re: To TPU or not to TPU...

They are made by Google for private use, and not sold. They are not more complex or expensive to produce than x86 CPU cores, but it doesn't seem there would be enough market for them to make development of something similar by other companies economically attractive. I don't know how far you would ...

Re: Google's AlphaGo team has been working on chess

I still don't understand. How do you get from 73 planes of size 8x8 a probability for each possible move ? First let's explain where the 73 comes from, in case anyone in this conversation doesn't know. Queens can move in 56 different ways (8 directions and up to 7 steps in each direction). This als...

Re: 2-part series that explains a0 better... 12/19/2017 ...

That sums up neural networks quite well but I would suggest everyone to get into the math of neural networks. The machine learning course by Andrew Ng (I think you can find it on coursera) is quite well and a good introduction. The term "neural-network" is sometimes a little bit fussy. It's all abo...

Re: To TPU or not to TPU...

Note that this video is not what I would call a clear explanation. For one, it is heavily geared towards an audience of mathematicians, using concepts these are familiar with. But which are actually not needed at all to understand what is going on, and would just make it complete mumbo-jumbo for th...

thanks for the video...

wow ... that was an awful lot in 5 min...

need to go back to school and learn calculus...
