I recently came across this paper Thermodynamic Natural Gradient Descent by Normal Computing. I found it very interesting, so below is my brief take on it.
🧠 Predictive Coding as a 2nd-Order Method
Published:
📖 TL;DR: Predictive coding implicitly performs a 2nd-order weight update via 1st-order (gradient) updates on neurons that in some cases allow it to converge faster than backpropagation with standard stochastic gradient descent.

♾️ Infinite Widths (& Depths) Part III: The Maximal Update Parameterisation (\(\mu\)P)
Published:
This is the third and last post of a short series on the infinite-width limits of deep neural networks (DNNs). In Part I, we showed that the output of a random network becomes Gaussian distributed in the infinite-width limit. Part II went beyond initialisation and showed that infinitely wide nets trained with GD are basically kernel methods.
