Following up on my post on microcrad — many of you liked and supported the project, thank you for that — I published a long-form piece on automatic differentiation, where I explain…

My experience on this project was that the checks proved to be useful way before I could run the program for the first time. The first version of the code had relatively few null c…

I haven’t really looked into performance comparisons with tensor-based frameworks. This was mainly a learning project, so my goal wasn’t to make it fast. My guess is that a scalar …

I love the idea! The next step is to add role play games in town squares.

Thank you for pointing this out, and to those adding clarifications to this statement as well. I've fixed the issue by renaming the reserved identifiers.

I re-read the second part with more calm once I got back home. There were at least a couple of things I wasn't familiar with (and therefore didn't even consider), specifically FAM …

I see, I agree that especially checking for null really comes to styles and opinions, I still don't have one I can call mine. Thanks for the explanation!

[deprecated post-edit] I guess I used function names beginning with underscore as it didn’t occur to me that it might be un-idiomatic. The intention was to make clear to myself tha…

ngl, it distracts from backprop itself a little, but teaches a lot about memory management. I did it this way because in parallel I wanted to get better at C, but if your aim is to…

In general yes, but not if you are disciplined. I’d put it this way: though the idea of ref counting felt very natural at the beginning for my use case, at some point I realized th…

Mainly did it for learning, as dgellow correctly presumed, but also there’s something intrinsically beautiful in writing code with zero dependencies

Hey HN, I'm Orazio. I built microcrad (with a 'c'), a tiny scalar-valued automatic differentiation engine, with a small multi-layer perceptron implementation on top. It's reimpleme…
