An introduction to SuperLearner, a loss-based ensemble prediction algorithm.

This presentation provides a brief introduction to SuperLearner package, an ensemble prediction algorithm developed by Eric Polley at the National Cancer Institute. SuperLearner allows the use many algorithms to generate an ideal prediction function that is a weighted average of all the algorithms considered. The SuperLearner package permits the integration of dozens of prespecified potential algorithms found in other R packages as well as 'wrappers' that provide the user with the ability to include their own algorithms.
