  • It’s hard to make a good weather forecast tool without theoretical elements incorporated in it.

    I’m sure the model produces higher accuracy results on historical data. I read the abstract and it’s not mentioned if they tested it on new data.

    With ml, the most difficult part of the work is making sure not to overfit historical data. Is target have a less accurate model (on the training data) than a model that can be justified using theoretical reasoning. This way, I can be much more confident that it will work in the long run.

    Let’s see where this will go in the coming years!

    I kept seeing this pop up recently, and I finally understand it: it’s an introductory problem in Lorentzian general relativity.

    AB is a space-like line, while AC is a time-like line. Typically, we would write AC as having distance of 1, but with a metric such that squaring it would produce a negative result. However it’s similar to multiplying i to the value.

    BC has a distance of 0, but a better way of naming this line would be that it has a null interval, meaning that light would travel following this line and experience no distance nor time going by.

    I’m sure PBS Spacetime would explain all of this better than me. I just woke up and can’t bother searching for the correct words on my phone.
