You mean a matrix multiplication processor?
You mean headless GPU? (Or, in some cases, DSP?)

#52Is it time to recognize that "AI" is the meaningless buzzword of 2017? "Nothing is cooler because it is cyber." -- J.D. Falk, RIP.
How is AI meaningless? I mean, I guess the term can be seen as silly, but I mentally map it to "statistical computing." [edit] Since I'm getting down votes, can someone clarify? I wasn't being contrarian with the above comment. Is my mental map of what AI means as an industry term incorrect?
An "AI" coprocessor could be an FPGA, a neuromorphic chip, a DSP, a TPU, or a GPU -- it's incredibly vague.

I suspect it will have more in common with mobile GPUs than the big iron ASICs that come from NVIDIA or AMD.
IMHO Its most likely a variant of the AMD GPU or APU, because it would take some major differentiation before nVidia would do a largely custom core processor, even for Microsoft. nVidia's Tegra Xavier SoC is under development, with the Volta GPU architecture that would include the Tensor core which is specifically intended for deep learning and AI applications.
That's doubltful. AMD is happy to provide bespoke chips for big customers (like the XBox) but what you want for inference is to multiply entire int8 matrixies in hardware dataflow. The silicon providing float32 support in an AMD GPU isn't needed and their dataflows only extend to vectors rather than matrices. In the case where the matrix you're multiplying is much bigger than the execution hardware you can throw at it this doesn't make a big difference in efficiently using adders. But using vectors rather than matrices is hugely wasteful of register read ports if you're always doing matrix operations and don't also have to excel at operations which are only vectors.

#54For people who understand neural networks, this is HUGE! I have been dreaming for a custom chip for neural networks for 5 years! If they pull it off and deliver a product launch in a year or two, then they would smoke the competition again.
Google has had their TPU out for a while now. And the next generation of NVidia GPU is supposed to have neural network accelerating hardware.

Your definition feels pretty reasonable, but I think the issue is that the term "AI" is being slapped on tons of services that do extremely basic predictions. If it has a formula in it, it's now "AI".

We got a couple at my company and I've built some protoypes for it, and threw up a little blog for it. The cool thing is the HoloToolkit which seems to be maintained by some xbox developers, and scripts all the functionality you need to get off the ground. The hard part has been coming up with prototypes that go beyond a cool experience, and solve some customer's problem. It doesn't recognize what it's looking at, as…
What is it about the beta Skype app that is so compelling?
I haven't used it, but I feel fairly certain that the killer app for VR/AR is going to be eye contact. Skype with eye contact would be a major leap forward. Eye contact lets you negotiate speaking/listening handoff in a natural way, instead of using awkward procedural norms.

AI has been a word since McCarthy coined it in 1955. It is always "just around the corner", but it is hardly a meaningless buzzword.

AI uses more than statistics. Some algorithms doesn't use statistics at all, for example you can build decision trees using information theory instead of statistics. Statistics is a big part of AI, but in most algorithms you will find more than just statistics like optimization, algebra, ...
Re: Second version of HoloLens HPU will incorporate AI coprocessor
#59I used a Hololens and it was awesome (it fit over my glasses). Inference on Hololens could make you do so much more. Maybe you could use it to take scans of parts from a CNC or the CNC tool and create a system that could tell you if a similar piece will fail in the future. From what I have seen compared to Google Glass I think it could be possible for richer interactions and also it uses both eyes. But, I haven't hea…
The use cases are pretty varied. We're using some for a medical study looking to see if the HL can help lessen pain through distraction (tested against normal distractions like iPads). The HL is nice, as it lessens incidents of simulator sickness. We're also trying to get the thing to be used to scan the homes and backyards of long-term stay patients so that they can 'go back home' for a little bit while hooked into…
The virtual home sounds more appropriate for VR than AR or am I missing something about the in hospital scenario - with AR you'd still see all the hospital just with some bright holograms trying to be "in front"
Re: Second version of HoloLens HPU will incorporate AI coprocessor
#60Any idea who makes it? It's probably close in architecture to GPUs, the kind of thing Nvidia and AMD are positioned to capitalise on.
My money is on Movidius:
