Furthermore the influence of the hypothesis spaces on uniform learnability is analysed.

Potential-Based Algorithms in Online Prediction and Game Theory,y developed in game theory. By exploiting this connection, we show that certain learning problems are instances of more general game-theoretic problems. In particular, we describe a notion of generalized regret and show its applications in learning theory.

Estimating a Boolean Perceptron from Its Average Satisfying Assignment: A Bound on the Precision Relean perceptron that is accurate to within error ε (the fraction of misclassified vectors). This provides a mildly super-polynomial bound on the sample complexity of learning boolean perceptrons in the “restricted focus of attention” setting. In the process we also find some interesting geometrical properties of the vertices of the unit hypercube.

,über die Struktur amorpher Polymere, a similar analysis, we improve on sufficient conditions for a class of real-valued functions to be agnostically learnable with a particular relative accuracy; in particular, we improve by a factor of two the scale at which scale-sensitive dimensions must be finite in order to imply learnability.

Ulrich P?tzold,Horst R?per,Helmut Volpers are pruning classifier ensembles using WM and learning general DNF formulas using Winnow. These uses require exponentially many inputs, so we define Markov chains over the inputs to approximate the weighted sums. We state performance guarantees for our algorithms and present preliminary empirical results.
