I was at an Nvidia presentation where they made a big deal about just being 'on-silicon' rather than having to go through copper connects (to a bus external to the chip). Each join, corner, etc adds to capacitance on the wire, wh

The 'big activity vector' language is partly a reference to the Vector Word Embedding stuff (see [1] for an explanation). The surprising thing about that is that it is possible to learn an embedded of individual words in a multi-

Wow, I'm surprised to see a comment so critical of Venture Capitalists on HN. But I guess it's fair: The VC industry as a whole badly underperforms the S&P index on a risk-adjusted basis. Or aren't those the asset manag

Agreed - what I don't understand is why most of the discussion here is about high valuations. The big reveal of the article is that the valuations are known by investors to be illusory - and (colloquially) the VCs are ripping the face

I'm going to assume your comment wasn't as mean as it appears in writing. Why am I here? Because I started my first business in college, then went into finance to get some 'real world' experience, and then went on to st

The reason that the emoticons are so well targeted is not for the users themselves. If someone includes one of the emoticons, it makes machine-identification of sentiment trivial (compared to reading and interpreting the text). (not sure w

Agreed - the title should be changed. Perhaps the submitter saw the Nvidia cards in there and read this as an OpenCL vs CUDA kind of thing, not seeing the principal cool-factor of OpenCL : that OpenCL interoperates across all these devices

The most remarkable take-away from this whole genre of word-embedding is that just by doing 'dumb averages' of word contexts and then optimizing the 'vector[word]' on the input (and output sides), you end up with a SEMAN
