Advanced Topic 36 of 51 Math for Computing

Convex Optimization

Optimizing convex functions with guaranteed global optima.

How it works

For convex functions every local minimum is global; problems like linear programs, least squares and SVMs are convex with efficient solvers; a function is convex if its Hessian is positive semidefinite.

Where it is used

Reliable optimization.

Common pitfall

Checking convexity before trusting a solver's result.

Where it fits in the course

Convex Optimization is topic 36 of 51 in Math for Computing, rated Advanced. It follows Optimization. The next topic is Lagrange Multipliers.
