### Re: Dimensionality of Monte Carlo

2d pdes are easier to solve than 1.4999 pde!
Very true. Sometimes you can treat 1.4999 as 2 - $\epsilon$, where $\epsilon$ is a perturbation
Same as Hausdorff dimension?

### Re: Dimensionality of Monte Carlo

Perhaps we can conclude from this discussion that the concept of dimensionality is not particularly useful in this context? Depends of course the dimension is integral or not! On a follow-on remark, can we not just ban all nouns completely and replace them by verbs as proposed by Swift's Laputan pr...

Epsilon is also yugely overloaded, see e.g. $\varepsilon$

### Re: About solving a transport equation

The OP post (deleted) is similar  to the rather innocuous-looking degenerate pde that crops up here and there $\frac{\partial u}{\partial t} - (1-y)^2\frac{\partial u}{\partial y} = 0$ on the interval $(0,1)$ (1) with initial condition $u(y,0) = f(y)$ on the interval $(0,1)$ (2) Qu...

Despite some evidence for top-down connections in the brain, there does not appear to be a global objective that is optimized by backpropagating error signals. Instead, the biological brain is highly modular and learns predominantly based on local information.  https://arxiv.org/pdf/1905.11786.pdf ...
