We present a unified duality view of several recently emerged spectral methods for nonlinear dimensionality reduction, including Isomap, locally linear embedding, Laplacian eigenmaps, and maximum vari...
Fat quality is determined by the composition of fatty acids. Genetic relationships between this composition and single nucleotide polymorphisms (SNPs) in the stearoyl-CoA desaturase1 (SCD1) gene were ...
The dimensionality of turbulence in uid layers determines their properties. We study electro- magnetically driven ows in nite depth uid layers and show that eddy viscosity, which appears as a res...
We study the integration and approximation problems for monotone and convex bounded functions that depend on $d$ variables, where $d$ can be arbitrarily large. We consider the worst case error for al...
Linear methods of dimensionality reduction are useful tools for handling and interpreting high dimensional data. However, the cumulative variance explained by each of the subspaces in which the data s...
Linear dimensionality reduction techniques, notably principal component analysis, are widely used in climate data analysis as a means to aid in the interpretation of datasets of high dimensionality. T...
A three-dimensional inverse groundwater flow and transport model that fits hydraulic- head and concentration data simultaneously using nonlinear regression is presented and applied to a layered sand...
In this paper we will look at the connection of frames and finite dimensionality. The focus is to present simple algorithms, which are available online. We will give basic algorithms to use with frame...
Studies to detect genes responsible for economic traits in farm animals have been performed using parametric linear models. A non-parametric, model-free approach using the ??expanded multifactor-dimen...
Valiant’s theory of holographic algorithms is a novel methodology to achieve exponential speed-ups in computation. A fundamental parameter in holographic algorithms is the dimension of the linear basi...

The N-dimensional Schrödinger equation involving a general, central potential VN(r), is decomposed into a 3-dimensional component plus a term that may be treated as a dimension-dependent perturba...
