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 ± …

Online learning with kernels

J Kivinen, AJ Smola… - IEEE transactions on …, 2004 - ieeexplore.ieee.org
Kernel-based algorithms such as support vector machines have achieved considerable
success in various problems in batch setting, where all of the training data is available in …

Approximate inference of functional dependencies from relations

J Kivinen, H Mannila - Theoretical Computer Science, 1995 - Elsevier
The functional dependency inference problem is the following. Given a relation r, find a set
of functional dependencies that is equivalent with the set of all functional dependencies …

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 …

Sequential prediction of individual sequences under general loss functions

D Haussler, J Kivinen… - IEEE Transactions on …, 2002 - ieeexplore.ieee.org
We consider adaptive sequential prediction of arbitrary binary sequences when the
performance is evaluated using a general loss function. The goal is to predict on each individual …

Relative loss bounds for multidimensional regression problems

J Kivinen, MKK Warmuth - Advances in neural information …, 1997 - proceedings.neurips.cc
We study on-line generalized linear regression with multidimensional outputs, ie, neural
networks with multiple output nodes but no hidden nodes. We allow at the final layer transfer …

Online learning with kernels

J Kivinen, A Smola… - Advances in neural …, 2001 - proceedings.neurips.cc
We consider online learning in a Reproducing Kernel Hilbert Space. Our method is computationally
efficient and leads to simple algorithms. In particular we derive update equations for …

[PDF][PDF] The perceptron algorithm vs. winnow: linear vs. logarithmic mistake bounds when few input variables are relevant

J Kivinen, MK Warmuth - Proceedings of the eighth annual conference …, 1995 - dl.acm.org
We give an adversary strategy that forces the Perception algorithm to make(N–k+ 1)/2 mistakes
when learning k-literal disjunctions over N variables. Experimentally we see that even for …

[PDF][PDF] Additive versus exponentiated gradient updates for linear prediction

J Kivinen, MK Warmuth - Proceedings of the twenty-seventh annual ACM …, 1995 - dl.acm.org
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*. …

[PDF][PDF] Hedging Structured Concepts.

WM Koolen, MK Warmuth, J Kivinen - COLT, 2010 - dare.uva.nl
We develop an online algorithm called Component Hedge for learning structured concept
classes when the loss of a structured concept sums over its components. Example classes …
