Some recent MCMC samplers such as ["Randomize-then-optimize"](https://epubs.siam.org/doi/10.1137/140964023) exploit least squares structure in the log-likelihood; i.e., the log-density has the form $f…

## Basic Problem
When I ran a grid search for optimizing the Savitzky-Golay filter parameters, I found that for high `polyorders`, the coefficients from `scipy.signal.savgol_coeffs` are numerically i…

Hi,
I’ve recently been having this weird issue where my discriminator losses tend to 0 quite quickly, while my generator losses tend to 1 (see photo). My understanding of GAN’s is that the optimal …

**Describe the bug 🐞**
`A \ b` works when `A` is of dimension $n\times p$ and $b$ is of dimension $n$. However, for `LinearSolve`, the code
```julia
using LinearSolve
lin_prob = LinearProblem(A,…
