From the crapper…. Why is Brainchip recently a Nr. 1 topic with AI created stuff?

Re the nuclear-detection paper comparing Akida, SpiNNaker and Loihi 2 there were comments that Akida delivered the fastest inference but lower accuracy due to the 4-bit quantisation constraint.

This raises the question which generation of Akida was actually tested?

I imagine most academic work still uses the first widely available Akida hardware (AKD 1000), which typically runs models in INT4 precision to maximise power efficiency. As far as I understand it, it's great for speed and edge deployment, but a lower precision naturally introduces quantisation error that can impact accuracy.

What’s interesting is that later iterations of the Akida architecture support higher precision and mixed-precision approaches (e.g. INT8). Presumably moving from 4-bit to 8-bit precision could entail a significant recovery of accuracy.In other words, if the same benchmark were run using higher-precision modes or newer Akida generations, you might see Akida maintain its inference-speed advantage while narrowing or (hopefully) even eliminating the accuracy gap with Loihi 2??

If so, it would be very interesting to see how the results change under those conditions.

On the end it’s a waiting game… as usual. Let’s see what we will see from now on! 🙏 🤞

Hi Bravo,

According to the Diogenese theory of everything, Akida 1000 (4-bit) may not be the ideal tool where mathematical precision in the output is required, but that does not necessarily detract from its utility in use cases where the benchmark is probability, such as video, speech, ...

4-bit allows 16 gradations, which means individual levels are ~ 6% apart, while 8-bit has 256. giving about 0.4% differentiation.

16-bit provides about 65k "levels" which is 1/256 th of 8-bit, (less than 1/500 th of 1%).

So basically, mathematical accuracy better than 6% error is difficult to achieve with Akida 1000, but where probability is concerned, that may not be such a hurdle.

Loihi 2 provides graduated quantization up to 32-bit:

It is also noteworthy that Intel 4 is in 4 nm while Akida 1000 is 28 nm. Comparing Akida 1000 with Loihi 2 does not do justice to Akida's tech advancements, but to have compared the Akida 2 on-line FPGE would also have underplayed the capabilities of the soon-to-be Akida 2 ASIC.

Do we have Renesas still on the books, what about Megachips
What you on about shitstick?

Given that Loihi 2 has uo to 32 bits, that means that it takes up a lot more wafer real estate than Akida 2 at the same architecture size (eg, 4 nm). This makes it much more expensive to make. I don't know the yield (working chips per wafer) but it tends to decrease with size, so, even though it is possible to fit more chips per wafer, the number that don't work will probably be higher than with a larger architecture.

... not to mention TENNs ...

... and solid state switching to replace packet switching ...

Good evening Diogenese ,

Interesting ones thoughts , thankyou as always.

Personally, is still truely bewildered.

WHAT THE FARK , a device to pick up elements in the atomic , seriously could damage life as one knows it ..... yet thay are STILL FUCKIN AROUND.

TRUELY BEWILDERD BY THE LACKSADASEYH ATTITULDE DISPLAYED BY THOSE THAT HAVE THE BUDGETS YET STILL ARE FUCKING AROUND AIMLESSLY.

In the mean time ..... apparently it's fine to spend many US $ Billions to locate & secure 400~500 Kg of atomic material in Iran.

One could only come to the conclusion , those in controle .... fark the people , solong as a few get to prosperous greatly , WHO CARES.

VERY , VERY SADE STATE OF AFFAIRS.

THE TECK IS THERE , WAITING , FUCKING USE IT.

Obviously not directed at you.


FAaaark Me Spinning.


Regards,
Esq.

Why are you worried its between me and him
Does he know that he's living in your head?

I'm worried because Wilzy hasn't posted on here in over 12months. Have you considered therapy?

If there was anything better than AKIDA1000 out there then i suggest Kevin Johnson, IBM would be using it for his system builds.
IMO these builds are warm ups for him. His builds will likely become more complex by the time he gets to AKD 2500/TENNs.

Not sure why he thinks Pom is Wilzy in any online shape or form...

I have linked some therapy support links below, as you may be right and this person needs to seek help.
