@ZhaiAndrew Are there any runbooks or best practices guides at least?

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.

@seanjtaylor @ItsMrLin might soon have an empirical answer: https://t.co/ISMdHGJ6l3

I think this is a discovery of comparable importance to the arrow in the FedEx logo.

It turns out that the Dragon 2 actually uses Chromium and Javascript for its flight interface. So there’s a reasonable chance this autopilot would run in the real Crew Dragon‽ @elonmusk, @NASA can you confirm?

I wrote a Javascript Autopilot for @SpaceX #CrewDragon https://t.co/0ENSPmK7ue

@preetkchauhan Data Carpentry's social science curriculum is a good place to start: https://t.co/rtG3lckQ8T (Disclosure: I taught for them). And if you're using existing data, you need to get familiar with the foreign package: https://t.co/oOg6qVUtGR

It's a 1 hidden-layer MLP with sigmoid activations, fit with SGD. Usage: set X and Y to numpy arrays of training feature/labels, resulting weights will be in variables w and e.
