OBE: Outlier by Example

Outlier detection in large datasets is an important problem. There are several recent approaches that employ very reasonable definitions of an outlier. However, a fundamental issue is that the notion of which objects are outliers typically varies between users or, even, datasets. In this paper, we present a novel solution to this problem, by bringing users into the loop. Our OBE (Outlier By Exa...

A 1994 University of Chicago study entitled The Social Organization of Sexuality found that on average men have 74% more opposite­gender partners than women, confirming a view that men are more promiscuous. But whoever reported this finding was lying or confused! We’ll show you how to use the properties of vertex degrees in a graph to prove this. Let’s recast opposite­gender partnering in graph...

Hemirings, Congruences and the Hewitt Realcompactification

The present paper indicate a method of obtaining the Hewitt realcompactification vX of a Tychonoff space X, by considering a distinguished family of maximal regular congruences, viz., those which are real, on the hemiring C+(X) of all the non-negative real valued continuous functions on X.

Look Closely: Lessons Prof. Gérard T. Simon Might Have Taught

This symposium honors Prof. Gérard T. Simon, a respected colleague in the field of ultrastructural pathology. Though he distinguished himself during the several decades of his career as an outstanding diagnostician, laboratorian, and investigator, he is perhaps best known as an educator and evangelist for the importance of electron microscopy, particularly for trainees. It is no surprise that t...
