this is less trivial than the stupid stuff I was laughing at earlier for grading, but almost half of the class doesn't know how to compute classification error

trying to use this equation from a conference article, but they made no effort to explain how they prevented the log of a negative scenario

and here's the brilliant code within this file to implement the assigned Harris corner detection algorithm

Intuatively, the limit should be about 3/2, since that is the expected value of each Xi, actual answer is 4/e (I was just assuming it was 3/2's which was tripping me up). I literally just needed use the strong law of large numbers on the natural log of that

What really kills me about this, is I kept second guessing myself, so I coded up a quick program to check that it did converge to 3/2's, and kept getting 1.47ish, which is 4/e, not 3/2!

Sort of, the trick is you take the natural log of this, then you have a sum of iid random variables over N, which then you can use the strong law of large numbers on like normal

I spent hours trying to figure out how to make this novel neural network structure work and then I made a typo in my code that fixed a stupid linear algebra error I had made

The fun part about playing an instrument made of wood, little tiny cracks like this will cost you 300 dollars to fix
