Does cost-sensitive learning beat sampling for classifying rare classes?

• Kate McCarthy, Bibi Zabar, Gary Weiss
• UBDM '05
• 2005

A highly-skewed class distribution usually causes the learned classifier to predict the majority class much more often than the minority class. This is a consequence of the fact that most classifiers… (More)

Traces, ideals, and arithmetic means.

• Victor Kaftal, Gary Weiss
• Proceedings of the National Academy of Sciences…
• 2002

This article grew out of recent work of Dykema, Figiel, Weiss, and Wodzicki (Commutator structure of operator ideals) which inter alia characterizes commutator ideals in terms of arithmetic means. In… (More)

An infinite dimensional Schur – Horn Theorem and majorization theory

• Gary Weiss
• 2010

The main result of this paper is the extension of the Schur–Horn Theorem to infinite sequences: For two nonincreasing nonsummable sequences ξ and η that converge to 0, there exists a positive compact… (More)

Improving classifier utility by altering the misclassification cost ratio

• Michelle Ciraco, Michael Rogalewski, Gary Weiss
• UBDM '05
• 2005

This paper examines whether classifier utility can be improved by altering the misclassification cost ratio (the ratio of false positive misclassification costs to false negative misclassification… (More)

THE COMMUTATOR STRUCTURE OF OPERATOR IDEALSKenneth

• Gary Weiss, Mariusz Wodzicki
• 1997

Additive commutators of operators belonging to two{sided ideals of B(H) are studied. J){commutators is characterized and found to equal IJ ; B(H)]. It is shown that three commutators are enough in I;… (More)

A SURVEY ON THE INTERPLAY BETWEEN ARITHMETIC MEAN IDEALS , TRACES , LATTICES OF OPERATOR IDEALS , AND AN INFINITE SCHUR-HORN MAJORIZATION THEOREM

• Victor Kaftal, Gary Weiss

The main result in [23] on the structure of commutators showed that arithmetic means play an important role in the study of operator ideals. In this survey we present the notions of arithmetic mean… (More)

Maximal functions and h spaces defined by ergodic transformations.

• R R Coifman, Gary Weiss
• Proceedings of the National Academy of Sciences…
• 1973

Suppose an ergodic flow acts on a probability space enabling us to introduce the Ergodic Hilbert transform f of f in L(p)(), 1 <== p <== infinity. H(1) is the class of all functions of the form f +… (More)

INTELLIGENT TELECOMMUNICATION TECHNOLOGIES

• Gary Weiss, John P. Eddy
• 1998

Telecommunication networks are extremely complex systems requiring high reliability and availability. The effective management of these networks is a critical, but complex, task. To help with this… (More)

Different rates of synthesis of whey protein and casein by alleles of the β-lactoglobulin and αs1-casein locus in cattle

• R. Graml, Gary Weiss, Josef Buchberger, Franz Pirchner
• Genetics Selection Evolution

Using Rules in Object-Oriented Designs

• Daniel Dvorak, Anil K Mishra, Johannes P. Ros, Anoop Singhal, Gary Weiss, Diane T. Litman
• 1996

System requirements often express some of the behavior of a domain model in the form of policies, constraints, invariants, and rules. Although an object-oriented approach helps with the design of… (More)
