Have you ever done a dense grid search over neural network hyperparameters? Like a *really dense* grid search? It looks like this (!!). Blueish colors correspond to hyperparameters for which training converges, redish colors to hyperparameters for which training diverges.

Golreich and Shridar (1995) is continuously being numerically falsified by high resolution turbulence simulations. This time in MRI driven turbulence at high resolutions, revealing k^-3/2 kinetic spectra and slow mode dominance. science.org/doi/10.1126/sc…
