Neural Network - Handwritten Digit Recognition

Hi all,

I've written a blog post on recognizing handwritten digits using neural
networks in Pharo.

http://www.samadhiweb.com/blog/2018.02.04.neural.networks.html

I attach here two screenshots built using Roassal showing good and bad
recognition outcomes. I must say Roassal is great!

Comments welcome here or on my blog.

Excellent indeed !

I will use it to show students ^^ and try tu improve the network.

Big Thx

nice,

the model can also be serialized for loading in other vm?

Thanks for sharing this. This is cool.
I set up a booklet Booklet-IANeurons for alex and a little book around
neural networks and your work could fit
there.

Yes. Serialized with STON on Linux 64-bit Pharo 6, materialized
and ran on Linux 32-bit Pharo 6 on another computer.

Happy to contribute to the book. The blog post content is already in Pillar.

Re: Neural Network - Handwritten Digit Recognition

Cool! I set it up so that each time people commit it will build automatically.
Now alex did not commit anything yet but it would be great to have
something about your approach.

Here is the link https://github.com/SquareBracketAssociates/Booklet-IA-Neurons
I can give you commit rights.

Stef, thanks for adding me to the repo. I've plugged my blog post in as chapter
1.

On Pillar, I see that the generated PDF shows the array inspector screenshot as
an outsized image. What's the best practice on sizing images?

Anyhow, I've set up Docker with the texlive:pillar image and just did a
successful test run. I can now experiment with agility. :-)

Re: Pillar Re: Neural Network - Handwritten Digit Recognition

you can change the size of the image using |width=60| it is expression
is given in %
I fixed it. I will read it and give you feedback.
Now I just skimmed throw it and I would
- structure the text with some sections like setup, importing,
computing, rendering, conclusions
- then I would turn the large roassal script in a tiny and beautiful class
