Exponentiated gradient versus gradient descent for linear predictors
J Kivinen, MK Warmuth - Information and computation, 1997 - Elsevier
We consider two algorithms for on-line prediction based on a linear model. The algorithms
are the well-known gradient descent (GD) algorithm and a new algorithm, which we call EG ± …

Averaging expert predictions
J Kivinen, MK Warmuth - European Conference on Computational …, 1999 - Springer
We consider algorithms for combining advice from a set of experts. In each trial, the algorithm
receives the predictions of the experts and produces its own prediction. A loss function is …
