AD 20
AD 20 (XX) was a leap year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Marcus Valerius Messalla Barbatus and Cotta (or, less frequently, year 773 Ab urbe condita). The denomination 20 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

gollark: Then, you just move it a little bit toward lower loss (gradient descent).
gollark: You have a big thing of settable parameters determining how you go from input to output. And if you know what the result *should* be (on training data), then as the maths is all "differentiable", you can differentiate it and get the gradient of loss wrt. all the parameters.
gollark: Well, you put your data into something something linear algebra and something something gradient descent, and answers come out.
gollark: I see. This might be one of the ones which can't boot from those, or you just beeized slightly.
gollark: That's one of the boot errors.
