1) Online learning
2) Kernel based machines
3) Prediction bounds
4) Reductions between learning problems
5) Unsupervised learning
We emphasize those techniques which are both theoretically analyzable and practically useful for a multitude of problems. Significant side notes and ancillary programs will be available online for future reference.
At the end of this class, students will have a working understanding of how to build (and avoid pitfalls of) working machine learning systems. For the covered topics, students will have an understanding of the state of the art sufficient to contribute to further academic development.
Anything which hasn't happened is speculation!
