The increasing availability of enormous data about users online, along with availability of sophisticated tools and technology to store, aggregate, and analyze data for secondary use has raised concerns about how to balance the opportunity for secondary use of data with the need to protect the user privacy that may result from harmful use. To develop a privacy protection mechanism that is usefu...

Sequential Pattern Mining is a widely addressed problem in data mining, with applications such as analyzing Web usage, examining purchase behavior, and text mining, among others. Nevertheless, with the dramatic increase in data volume, the current approaches prove inefficient when dealing with large input datasets, a large number of different symbols and low minimum supports. In this paper, we ...

To Ed EEros, on the occasion of his 60th birthday. We prove a local nite dimensional approximation result for unital C*-algebras that are simple, have a trace, contain suuciently many projections and are quasidiagonal.

In this study, we analyzed whether parents' receipt of welfare affects children's educational attainment in early adulthood, independent of its effect through changing family income. We used data from the Panel Study of Income Dynamics with information on parents' welfare receipt over the first 15 years of childhood. Cross-sectional results show that greater exposure to welfare is significantly...

Viewing vector/matrix multiplications as " projections onto linear subspaces " is one of the most useful ways to think about these operations. In this note, I'll put together necessary pieces to achieve this understanding.

We examine the relation between firms’ financial structures and their risky investment strategies in Taiwan’s banking industry. Regressions cover two subperiods: before the first financial reform (1996– 2000) and after the first financial reform (2001–2006), to address the impacts of the first financial reform on banking firms’ financial structures. Our first result demonstrates that the restri...

Let ϕ be a real-valued plurisubharmonic function on [Formula: see text] whose complex Hessian has uniformly comparable eigenvalues, and let [Formula: see text] be the Fock space induced by ϕ. In this paper, we conclude that the Bergman projection is bounded from the pth Lebesgue space [Formula: see text] to [Formula: see text] for [Formula: see text]. As a remark, we claim that Bergman projecti...

Figure-ground assignment to a contour is a fundamental stage in visual processing. The current paper introduces a novel, highly general dynamic cue to figure-ground assignment: "Convex Motion." Across six experiments, subjects showed a strong preference to assign figure and ground to a dynamically deforming contour such that the moving contour segment was convex rather than concave. Experiments...

Introduction. A general question which is of interest is the following. Suppose that ƒ is a mapping of a compact metric continuum X onto a metric space F. Under what conditions is there an embedding of X and Y in E (Euclidean n-space) or H (Hubert space) so that ƒ is topologically equivalent to a projection onto Y defined by some collection of parallel hyperplanes? Theorem 1 below provides an a...
