#AutoDiff
Yeah, I didn't quite understand the distinction between autodiff and symbolic differentiation for a while. The analogy of running back a sequence of operations on a tape I found very helpful to understanding, basically never needing to create a closed form representation

Reading about autodiff and it's really quite nuts that this was discovered in the freakin 60s (backwards pass in early 70s). What an absurdly clever technique

Every gradient in deep learning is matrix calculus. Almost nobody who ships models can do it by hand.

Autodiff made that survivable, not unnecessary. The moment a loss surface misbehaves, or a Jacobian needs interpreting, you are back to the mathematics.

Houston Team Maps Quantum Response Between Models
SAKE now delivers spectroscopic responses without recalculating spectra for each new quantum system configuration. Previously reliant on impractical symbolic differentiation as dimensionality increased, accurate predictions are now achieved via automatic differentiation and pathway transport operators. This expansion accurately reproduces projected transport, revealing previously hidden mechanisms within quantum dynamics.

Same's true of NNs - you no longer have to calculate autodiff layers by hand, you just import jax/torch and stack layers. Or Bayes - no need to write your own MCMC, you just use Stan/PyMC/(etc)

Watched Bob Carpenter's StanCon talk and decided the Stan stack deserved some love. PRs incoming to stan-math, stanc3, bridgestan + walnutpie: −15% walltime per gradient, a silent autodiff blowup on degenerate eigenvalues (ESS 29→411 when fixed), and a small pile of bugs 👀 :3

The real win: the gradient becomes one sparse solve of the fixed-point condition instead of backprop through the whole iterative contraction. The environment's near-degenerate fixed point is exactly what makes autodiff unstable in PEPS — this is what makes 2D variational TNs actually usable.

It also implemented an hamiltonian monte carlo "hello world" for me using Rust std::autodiff (while teaching me Rust).

This is so niche.
I found this on my phone from 2023.
I don't remember it, 2019-2024 I was indeed talking a lot to both when I sZ working on Autodiff
