Functional Equivalence between Radial Basis Function Networks and Fuzzy Inference Systems
, 1993
"... This short article shows that under some minor restrictions, the functional behavior of radial basis function networks and fuzzy inference systems are actually equivalent. This functional equivalence implies that advances in each literature, such as new learning rules or analysis on representational ..."

Bounded geometries, fractals, and lowdistortion embeddings
"... The doubling constant of a metric space (X; d) is thesmallest value * such that every ball in X can be covered by * balls of half the radius. The doubling dimension of X isthen defined as dim(X) = log2 *. A metric (or sequence ofmetrics) is called doubling precisely when its doubling dimension is ..."

This is a robust class of metric spaceswhich contains many families of metrics that occur in applied settings.We give tight bounds for embedding doubling metrics into (lowdimensional) normed spaces. We consider bothgeneral doubling metrics, as well as more restricted families such as those
Jewish Occupational Selection: Education, Restrictions, or Minorities? ∗

"... This paper documents the major features of Jewish economic history in the first millennium to explain the distinctive occupational selection of the Jewish people into urban, skilled occupations. We show that many Jews entered urban occupations in the eighthninth centuries in the Muslim Empire when ..."

there were no restrictions on their economic activities, most of them were farmers, and they were a minority in all locations. Therefore, arguments based on restrictions or minority status cannot explain the occupational transition of the Jews at that time. Our thesis is that the occupational selection
Treewidth: Algorithmic techniques and results

Any opinions expressed here are those of the author(s) and not those of the institute. Research disseminated by IZA may include views on policy, but the institute itself takes no institutional policy positions. The Institute for the Study of Labor (IZA) in Bonn is a local and virtual international research center and a place of communication between science, politics and business. IZA is an independent nonprofit company supported by Deutsche Post World Net. The center is associated with the University of Bonn and offers a stimulating research environment through its research networks, research support, and visitors and doctoral programs. IZA engages in (i) original and internationally competitive research in all fields of labor economics, (ii) development of policy concepts, and (iii) dissemination of research results and concepts to the interested public. IZA Discussion Papers often represent preliminary work and are circulated to encourage discussion. Citation of such a paper should account for its provisional character.

and Minority Students

"... Currently, students from lowincome backgrounds are underrepresented at selective colleges and universities in the U.S. With the introduction of many programs aimed at increasing the numbers of these students at selective institutions, it is important to understand how the characteristics of an inst ..."

Using restricted data from the National Education Longitudinal Study of 1988 and the National Longitudinal Survey of Freshmen, this paper finds that students from lowincome families at more selective institutions achieve lower grade point averages than other
On Matroid Representability and Minor Problems
"... In this paper we look at complexity aspects of the following problem (matroid representability) which seems to play an important role in structural matroid theory: Given a rational matrix representing the matroid M, the question is whether M can be represented also over another specific finite fiel ..."

Permutation Reconstruction from Minors
"... We consider the problem of permutation reconstruction, which is a variant of graph reconstruction. Given a permutation p of length n, we delete k of its entries in each possible way to obtain ( n) k subsequences. We renumber the sequences from 1 to n−k preserving the relative size of the elements to ..."

Minorities, media, marketing and marginalization

Given that increased rates of population movement across borders in recent decades have coincided with an era in which audiences for mass media are being fragmented and ever more precisely targeted according to demographic criteria, we might expect to find that ethnic minorities have become exposed ..."

Are minorities overrepresented in crime?

We explore whether socioeconomic status may explain this overrepresentation in the criminal justice system through the ..."

Restricting to this subpopulation, we do not find any evidence of overrepresentation: the proportion of juvenile offenders belonging to minorities is of the same order of magnitude as their share in the overall urban juvenile population living below the poverty
