Pi4 "networked AI core"?

Sat Oct 05, 2019 12:02 am

Specs for the 4 include the phrase "networked AI core" - Can anyone explain to me exactly what that is? I've been a software engineer for 35 years, I like to think I'm not a moron and I have a fair bit of experience with the Pi 3B. And I thought I knew what "AI" meant. Can someone enlighten me?

Which specs ? where did you see this ?

I found it just in the original 24/6 tweet..
Announcing #RaspberryPi4: your tiny, dual-display, desktop computer…and robot brains, smart home hub, media centre, networked AI core, factory controller, and much more:
The dont list it as a feature or "spec" , they list it as something the Pi can "become".

Just FYI it's on the MAIN PAGE for the product
https://www.raspberrypi.org/products/ra ... 4-model-b/
and it definitely doesn't even come CLOSE to implying that "you MAY be able to DO THIS and THAT with our board".
But all that being said - I know a tad about AI, not to mention a fair bit about hardware, software and related terminologies.
And "networked AI core" - sorry - but I've never heard of such a thing.

Smells to me like more rotted marketing soul-less drones.
Like "3D" toothpaste (thank you Crest).

What a world.

It's a fine product on it's own - no need for the devious dishonesty.

Cut and pasted from your link:

"Your tiny, dual-display, desktop computer …and robot brains, smart home hub, media centre, networked AI core, factory controller, and much more"

What that says to me is that *with the right software* it can do these things- as of course could any other SBC, with varying degrees of efficiency. Without the right software, it's not much use as a desktop computer either. You could also paraphrase the concept list as "...and the sky's the limit" but that's a bit overused- at least they do make some specific suggestions.

"networked AI core" is not specifically familiar to me, but I get the implication it has networking and it has enough memory and speed to run deep learning models of some useful size, thereby forming the core of some kind of embedded machine learning application.

Very obviously "networked AI core" is a reference to using the Pi with AI products and projects that have been available for some years now:

We've even had a forum subsection here dedicated to such things for ages:

Well Alexa needs to be updated for Pi4, it does not work yet.
Still based on Stretch?
https://github.com/alexa/avs-device-sdk

I have no idea what hardware is in those smart home hubs.
https://www.openhab.org/
https://smarthome.university/home-assis ... assistant/
But the Pi4 is probably now over the line in the capability department.

So do you buy a "Smart Home" setup that could be hacked or make your own with Pi's?
Anyone could have an Ironman JARVIS?

I have compiled ARM's Compute Library on 3's and 4's.
Still lots of other things like TensorFlow, Caffe, Leaf etc to try.
Some of these had issues with the older Pi's but just compile now.
Will full TensorFlow 2.0 work as well as Lite?
TensorFlow is tested and supported on the following 64-bit systems:
64 bit only?

Computer Vision now has more power, enough to do more complex stuff locally?
AL/MM/NN/CV etc software libraries all get a boost and are much closer to mainstream Linux.

Networked AI is where the models are trained somewhere else on big machines then run locally.
10,000 images is normal for training to teach a computer the difference between a cat and dog.
Once that model is learned then it could run on a local Pi.
Think of it as training the brains neurons to tell cats and dogs apart.
Once that "Neural network" has learned that "brain" can be copied to a local Pi.
