We describe a new boosting algorithm which generates only smooth distributions which do not assign too much weight to any single example. We show that this new boosting algorithm can be used to...

Efficiency versus convergence of boolean kernels for on-line learning algorithms (2001)

Roni Khardon, Dan Roth, Rocco A. Servedio

The paper studies machine learning problems where each example is described using a set of Boolean features and where hypotheses are represented by linear threshold elements. One method of increasing...

Martingale boosting (2001)

Philip M. Long, Rocco A. Servedio

Abstract. Martingale boosting is a simple and easily understood technique with a simple and easily understood analysis. A slight variant of the approach provably achieves optimal accuracy in the...

Quantum versus Classical Learnability (2000)

Servedio, Rocco A., Gortler, Steven J.

We consider quantum versions of two well-studied classical learning models: Angluin's model of exact learning from membership queries and Valiant's Probably Approximately Correct (PAC) model of...

Computational Sample Complexity and Attribute-Efficient Learning (2000)

Rocco A. Servedio, Rocco Servedio

Two fundamental measures of the efficiency of a learning algorithm are its running time and the number of examples it requires (its sample complexity). In this paper we demonstrate that even for...

PAC Analogues of Perceptron and Winnow via Boosting the Margin (2000)

Rocco Servedio Division, Rocco A. Servedio

We describe a novel family of PAC model algorithms for learning linear threshold functions. The new algorithms work by boosting a simple weak learner and exhibit complexity bounds remarkably similar...

Boosting and hard-core sets (1999)

Adam R. Klivans, Rocco A. Servedio

This paper connects two fundamental ideas from theoretical computer science: hard-core set construction, a type of hardness amplification from computational complexity, and boosting, a technique from...

On PAC Learning Using Winnow, Perceptron, and a Perceptron-Like Algorithm (1999)

Rocco A. Servedio

In this paper we analyze the PAC learning abilities of several simple iterative algorithms for learning linear threshold functions, obtaining both positive and negative results. We show that...
