Re: Computations in the exam

You do not need to do an eigenvalue decomposition by hand or similar, but small computations and derivations will be a part of the exam for sure.
And you do not need to memorize densities explicitly, if you understand the concept, you can write them down. Additionally, you still have the cheat sheet..

Re: SVM Solver and Testing

1) First, your are allowed to use optimization and solver libraries for the SVM part! The only numpy constraint is only for the neural network part! So cvxopt is fine here!

2) Some constrain? What do you mean? Dont get that question sorry.

If it's not just a typo, you are missing the inverse of the second sigma.

Re: Optimization Refresher Slide 24

Concave/convex functions have the property that they have only one optimum and so local optimum = global optimum.
That makes the optimization much easier.
