In light of the recent changes of UC Berkeley’s grading scheme to P/NP, it’s quite interesting to examine the problem of grading through a Game Theoretic perspective. Lots of students have proposed that the change to an online format encourages cheating, and that the curves for this semester will change drastically as a result. In this essay, I hope to explore this claim and test its validity.
Today’s Fact: Foot On Water
Andi came up with an insane question: How wide does a human foot have to be for a human to stand on water? Of course, he came up with something insane, reproduced here.

Linear Discriminant Analysis, or LDA for short, is an ML model used in classification. Specifically, for a model of
ntraining points, it assumes that the
dfeatures are all distributed Normally (Gaussian), with the same variance. More formally, taken from my professor’s cs189 notes, we get:
