The main point of this is that natural gradient descent is a second-order method. The main GD update equation is: ∇̃L(θ) = F⁻¹∇L(θ) which requires solving a linear system. For this, you can use the methods from the author's previous paper [Thermodynamic Linear Algebra](https://arxiv.org/abs/2308.05660). Since it's hard to implement a full neural network on a thermodynamic computer, the paper suggests running one in parallel to a normal GPU. The GPU computes F and ∇L(θ), but offloads the linear system to the thermo computer, which runs in parallel to the digital system (Figure 1). It is…
