10-601 Ensembles 2
From Cohen Courses
Slides
- Slides in PowerPoint.
- Margin "movie" I showed in class: Margin movie.
Readings
- Ensemble Methods in Machine Learning, Tom Dietterich
- A Short Introduction to Boosting, Yoav Freund and Robert Schapire.
- Optional: Improved boosting algorithms using confidence-rated predictions, Robert Schapire and Yoram Singer. (This paper has the analysis that I presented in class.)
Summary
You should understand the basic intuitions behind the analysis of boosting
- As reducing an upper bound on error and hence fitting the training data
- As a coordinate descent optimization of the same upper bound
You should also be aware that boosting is related to margin classifiers
