Classical Mechanics
Today I read some more of Goldstein to get caught up to the lectures I’ve been following. I made it all the way through multiparticle systems, and up next is constraints and the Lagrangian. Woo!
ISLR
I got into ISLR some as well. I went over smoothing splines and how to create and use them. Smoothing splines are pretty interesting: instead of forcing smoothness through adding an $Ax+Bx^2+Cx^3$ term, we use
$$ \sum_{i=1}^n (y_i-g(x_i))^2 + \lambda \int g''(t)^2 dt $$This forces smoothness with the second term: no matter what the rest of the function does, when you take the second derivative that right hand term sticks around! The term on the right is no joke, either! It ensures that the function passes through all the points of the training data. “But Jerry”, an astute reader might ask, “wouldn’t this cause overfitting?” The answer may SHOCK you! No! In the limit as the dataset approaches infinity, the degrees of freedom approaches a constant!
So how do we pick the right $\lambda$? One possible way is through cross-validation. It turns out that LOOCV can be computed very efficiently for smoothings splines!
Marsbound
After that I started getting some work done on Marsbound. I need to draw a background image for the options menu on the start page. After that I’ll work on the CharGen scene, where players build their team.
