Relative Loss Bounds and Polynomial-time Predictions for the K-LMS-NET Algorithm  M. Herbster, Proceedings of The 15th International Conference on Algorithmic Learning Theory, October 2004.

An online algorithm is given whose hypothesis class is a union of parameterized kernel spaces, for example the set of spaces induced by Gaussian kernel when the width is varied. We give relative loss bounds and a tractable algorithm for specific kernels.

Exponentially many local minima for single neurons Peter Auer, Mark Herbster and Manfred Warmuth, Neural Information Processing Systems 1996
We show that for a single neuron with the logistic function as the transfer function the number of local minima of the error function based on the square loss can grow exponentially in the dimension.
Tracking the best expert [Long Version] Mark Herbster and Manfred Warmuth, Machine Learning, Aug. 1998, vol.32, (no.2):151-78
We generalize the recent worst-case loss bounds for on-line algorithms where the additional loss of the algorithm on the whole sequence of examples over the loss of the best expert is bounded. The generalization allows the sequence to be partitioned into segments and the goal is to bound the additional loss of the algorithm over the sum of the losses of the best experts of each segment. This is to model situations in which the examples change and different experts are best for certain segments of the sequence of examples. In the single expert case the additional loss is proportional to $\log n$, where $n$ is the number of experts and the constant of proportionality depends on the loss function. When the number of segments is at most $k+1$ and the sequence of length $\ell$ then we can bound the additional loss of our algorithm over the best partitioning by $O(k \log n + k \log(\ell/k))$. Note that it takes the same order of bits to denote the sequence of experts and the boundaries of the segments. When the loss per trial is bounded by one then we obtain additional loss bounds that are independent of the length of the sequence. The bound becomes $O(k\log n+ k \log(L/k))$, where $L$ is the loss of the best partition into $k+1$ segments. Our algorithms for tracking the best expert are simple adaptations of Vovk's original algorithm for the single best expert case. These algorithms keep one weight per expert and spend $O(1)$ time per weight in each trial.
RNA Modeling Using Gibbs Sampling and Stochastic Context Free Grammars, Leslie Grate, Mark Herbster, Richard Hughey, David Haussler I. Saira Mian, and Harry Noller, Proceedings of Intelligent Systems in Molecular Biology 1994
A new method of discovering the common secondary structure of a family of homologous RNA sequences using Gibbs sampling and stochastic context-free grammars is proposed. Given an unaligned set of sequences, a Gibbs sampling step simultaneously estimates the secondary structure of each sequence and a set of statistical parameters describing the common secondary structure of the set as a whole. These parameters describe a statistical model of the family. After the Gibbs sampling has produced a crude statistical model for the family, this model is translated into a stochastic context-free grammar, which is then refined by an Expectation Maximization (EM) procedure to produce a more complete model. A prototype implementation of the method is tested on tRNA, pieces of 16S rRNA and on U5 snRNA with good results.
