...which can be used in optimisation or inference schemes like MCMC where thousands of action potentials at different parameter values are required, reducing the computation time by up to 70%. Open source Julia code provided. 🧵6/6 (very nice copyediting in Physica D with marked up LaTeX changes 😀)
Pairwise MCMC posterior samples from inference of parameters in our Noble1962-with-concentrations model.

We used to call it 'machine learning' and it was super useful for analysing large batches of images in scientific, medical, and historical research. But nobody used it to generate 'new' images based on real data because that was, and still is, extremely dumb.

Your college professor teaches you "A-stable methods are required for stiff ODEs". But PSA, the most commonly used stiff ODE solvers (adaptive order BDF methods) are not A-stable. #sciml #numericalanalysis #diffeq www.youtube.com/shorts/hmKVQ...

The most commonly used stiff ODE solver isn't A-stable?!?!?
