activatedgeek/LeNet-5 use ONNX for inference Updated 2025-07-16
Note that:
- the images must be drawn with white on black. If you use black on white, it the accuracy becomes terrible. This is a good very example of brittleness in AI systems!
- images must be converted to 32x32 for
lenet.onnx, as that is what training was done on. The training step converted the 28x28 images to 32x32 as the first thing it does before training even starts
We can try the code adapted from thenewstack.io/tutorial-using-a-pre-trained-onnx-model-for-inferencing/ at lenet/infer.py:and it works pretty well! The program outputs:as desired.
cd lenet
cp ~/git/LeNet-5/lenet.onnx .

./infer.py 9.png9We can also try with images directly from Extract MNIST images.and the accuracy is great as expected.

Ilana Wisby Updated 2025-07-16
Founding CEO of Oxford Quantum Circuits.
As mentioned at www.investmentmonitor.ai/tech/innovation/in-conversation-with-oxford-quantum-circuits-ilana-wisby she is not the original tech person:Did they mean Oxford Sciences Enterprises? There's nothing called "Oxford Science and Innovation" on Google. Yes, it is just a typo oxfordscienceenterprises.com/news/meet-the-founder-ilana-wisby-ceo-of-oxford-quantum-circuits/ says it clearly:
she was finally headhunted by Oxford Science and Innovation to become the founding CEO of OQC. The company was spun out of Oxford University's physics department in 2017, at which point Wisby was handed "a laptop and a patent".
I was headhunted by Oxford Sciences Enterprises to be the founding CEO of OQC.

Why Ciro Santilli refers to himself in the third person Updated 2025-07-16
Because when this gets converted to a OurBigBook.com page, it will be easier for people to copy paragraphs/fork and write a canonical page about Ciro.
What do you do when creating a pull request? Do you say "I", which is not true because Ciro did not say that, or do you say "John Doe thinks" bla bla?
And because his name is awesome! :-) Just kidding.
This became a micro-meme in 4chan:Correction: cirosantilli.com is not Ciro Santili's resume. It is your life.
- 2020-09-21 archive.vn/wip/Zz7fx (original) "ITT: weird sites you found by accident" a comment reads:
cirosantilli.com/ this is some guys resume who repeats his own name well over 1,000 times.
- 2020-04-30 archive.is/LgDbK (original) "Interesting Website thread" a comment reads:cirosantilli.com/ What is even this?
Royal Institution Updated 2025-07-16
Why do the electron and the proton have the same charge except for the opposite signs? Updated 2025-07-16
Given the view of the Standard Model where the electron and quarks are just completely separate matter fields, there is at first sight no clear theoretical requirement for that.
As mentioned e.g. at QED and the men who made it: Dyson, Feynman, Schwinger, and Tomonaga by Silvan Schweber (1994) chapter 1.6 "Hole theory", Dirac initially wanted to think of the holes in his hole theory as the protons, as a way to not have to postulate a new particle, the positron, and as a way to "explain" the proton in similar terms. Others however soon proposed arguments why the positron would need to have the same mass, and this idea had to be discarded.

People could freely comment their thoughts and sign below, making it much closer to what Ciro Santilli wants OurBigBook.com to be. But with upvotes ;-)
